The charge of weaponization has been raised across the political spectrum, especially in anti-Zionist discourse on the left and right. Scholars
John Mearsheimer and
Stephen Walt in the 2000s and Matthew Abraham in the 2010s suggested that the charge of antisemitism was becoming less effective when applied to criticisms of Israel. While warning in 2010 against denying or minimizing antisemitism, attorney and academic
Kenneth L. Marcus also cautioned against overuse of the "anti-Semitism card", paralleling concerns raised by
Richard Thompson Ford with the broader misuse of "the
race card": that it can be dishonest and mean-spirited, risks weakening legitimate accusations of bigotry, risks distracting socially concerned organizations from other social injustices, and hurts outreach efforts between Jewish and Arab or Muslim groups.
Israel and Zionism Some activists and scholars have said that weaponization of antisemitism, and
new antisemitism in particular, has been used to stifle criticism of Israel. In the early 1950s, U.S. journalist
Dorothy Thompson, a former advocate of Zionism, was publicly called antisemitic when she began to criticize Zionism after a visit to Palestine in 1945. Thompson felt the accusations, which persisted throughout her career, amounted to a "type of blackmail" or
character assassination. Professor
Lyndsey Stonebridge wrote, "today, many see the silencing of a bold humanitarian advocate in her story, and it is not difficult to understand why", but also that "there can be no doubt that anti-Semitism was a theme in Thompson's later writing." In his 1956 memoir, British military officer
John Bagot Glubb denied accusations of antisemitism for his criticism of Israel, writing: "It does not seem to me to be either just or expedient that similar criticisms directed against the Israeli government should brand the speaker with the moral stigma generally associated with anti-Semitism."
Stephen Rosenfeld wrote in 1982 that, in response to the notion that criticism of Israel can euphemistically conceal antisemitism, some critics of Israel "now routinely start out by asserting that of course they are going to be smeared as anti-Semites for their remarks [...] These attempts too often sound like a tacit attempt to identify Jews as people whose first loyalty is to a troublesome group outside America." Rosenfeld wrote that he found this current deeply troubling, even as he condemned attempts to intimidate critics of Israel. In 1989,
Cheryl Rubenberg wrote that it was "a common practice among Israel's advocates" to call opponents of "the [Israel] lobby's positions" or supporters of a Palestinian homeland antisemitic, referring to incidents involving U.S. politicians
Charles Mathias,
Pete McCloskey, and
Jesse Jackson. In a 1992 book, the American diplomat emeritus
George Ball wrote that
AIPAC and other pro-Israel groups "employ the charge of 'anti-Semitism' so carelessly as to trivialize it", suggesting that this was due to the lack of any "rational argument" with which to defend the state's actions. Critics such as the Israel–Palestine researcher
Suraya Dadoo, journalist
Ben White, and Associate Professor of English at the
University of Arizona Matthew Abraham have suggested that international Israeli advocacy groups have charged prominent people who express pro-Palestinian sentiment, such as
Jimmy Carter and
Desmond Tutu, with antisemitism. Abraham says this is a form of "political correctness" that undermines "greater understanding about the conditions producing conflict in the Israel–Palestine conflict". In 2002, Tutu said, "to criticise [Israel] is to be immediately dubbed anti-Semitic, as if the Palestinians were not Semitic ... People are scared in this country [the US] to say wrong is wrong because the Jewish lobby is powerful—very powerful." South African Muslim scholar
Farid Esack wrote that it was unfortunate that Tutu's statement "verged into antisemitic tropes" but "this misspoken moment unfolded because of his prophetic support of Palestinians". In the 21st century, various writers have suggested that charges of antisemitism in discussions of Israel can have a
chilling effect, deterring criticism of Israel due to fear of being associated with beliefs linked to antisemitic
crimes against humanity such as
the Holocaust. In 2004,
Joel Beinin wrote that the
Anti-Defamation League (ADL) and other organizations used the "well-established ploy" of conflating criticism of Israel with antisemitism, exposing Jews to attack by suggesting they are responsible for the Israeli government's actions. In a 2005 interview with
Campus Watch,
Norman Finkelstein said, "Whenever Israel faces a public relations debacle such as the Intifada or international pressure to resolve the Israel-Palestine conflict, American Jewish organizations orchestrate this extravaganza called the 'new anti-Semitism.'"
Jonathan Judaken said Finkelstein's dismissal of new antisemitism was "the mirror-image of the alarmists he seeks to denounce". In 2008, Finkelstein said that organizations such as the ADL had advanced charges of new antisemitism since the 1970s "to exploit the historical suffering of Jews in order to immunize Israel against criticism". Finkelstein has said that use of "the anti-Semitism card" attempts to displace "fundamental responsibility for causing the conflict from Israel to the Arabs, the issue no longer being Jewish dispossession of Palestinians but Arab 'opposition' to Jews". He compared claims of antisemitism against critics of Israel to
Soviet censorship. In
The Israel Lobby and U.S. Foreign Policy (2008),
John Mearsheimer and
Stephen Walt wrote that Israel's supporters have sought to shield it from criticism and pressure using fears of a "new antisemitism", naming as examples ADL publications raising concerns of antisemitism at moments of particular political pressure against Israel. They wrote that the charge of antisemitism can discourage others from defending in public those against whom the charge has been made. They said that rhetorical accusations of antisemitism put a
burden of proof on the accused person, putting them in the "difficult" position of having to prove a negative. They wrote, "we should all be disturbed by the presence of genuine anti-Semitism", but suggested that "playing the anti-Semitism card stifles discussion" and "allows myths about Israel to survive unchallenged". In 2010,
Kenneth L. Marcus wrote that although Mearsheimer and Walt called such accusations "the Great Silencer", they had not themselves been silenced, having received a wide audience for their book and appearances. Marcus also wrote that many pro-Israel commentators had also taken pains to say that not all criticism of Israel is antisemitic.
Ross Douthat wrote that the Mearsheimer and Walt are more the beneficiaries of "a calculated decision to take a highly-polemical approach to a hot-button topic" than they are victims of a supposed "suffocating and dangerous atmosphere of lockstep philo-Zionism in the American intelligentsia". Debates about the "antisemitism card", Douthat wrote, take place in a political environment where explicit political antisemitism is a "live and potent political force", whereas "race card" debates take place in a context where racism has been banished from open expression and exists only in "the realm of symbolism and subliminal messaging". The
Community Security Trust's 2008 report on antisemitic discourse in Britain says that, despite British Jewish community leaders' statements that Israel is legitimately subject to criticism, "some mainstream media commentators and political activists regularly accuse Jewish representative bodies of manipulating antisemitism as a smear with which to target any criticism of Israel." The report says that British Jewish representatives who raise concerns about antisemitism "are often treated with derision and contempt" and that "the false accusation [of manipulating antisemitism to smear Israel's critics] is often accompanied by the claim that politicians and journalists are too fearful for their careers and personal safety to speak out against Israel and the alleged Jewish cover-ups on its behalf. This charge is partly reliant upon the antisemitic notion of an all pervasive and all powerful pro-Israeli conspiracy." In 2009,
Tamar Meisels wrote that it is "very convenient for Jews, Israelis and Americans… to counter political attacks with the victim's cry of anti-Semitism. After all, in the post-Nazi era, no one wants to appear anti-Semitic. After the gas chambers, it is hardly bon ton to be an anti-Semite. So such accusations should be enough to shut anyone up." But she notes that many criticisms of Israel are antisemitic, giving the example of antisemitic tropes in statements by two western writers,
Breyten Breytenbach and
Jose Saramago. Responding to her article,
Brian Klug agreed that unwarranted accusations "devalue the word [antisemitism], cheapen the charge and alienate people of goodwill", but that antisemitic criticisms of Israel exist and should be called out as such. The next year, Klug wrote: "Critics of Israel, crossing an invisible line in the sand, find themselves accused of anti-Jewish hatred (or self-hatred if Jewish). They react by accusing their accusers, alleging that so-called antisemitism is nothing more than a machination of 'the Israel lobby'. At once, this is seized upon as an antisemitic slur; which in turn is denounced as a Zionist smear. Round and round they go, down and down they go, in a circle that gets ever more vicious. One of the depressing things about this vicious circle is that so many virtuous people—people of goodwill—get caught up in it." Commenting on a 2015
Campaign Against Antisemitism (CAA) poll of British Jews that found that 77% of respondents had "witnessed antisemitism that was disguised as a political comment about Israel",
Jonathan Sacerdoti said, "often people are told that it's the other way around—that Jews silence criticism of Israel by invoking antisemitism [... the results show that] there are people who use a legitimate debate about Israel to prevent Jews from speaking out when they feel they have been the victims of antisemitism." In 2019, Joshua Leifer, an editor of
Dissent magazine, wrote that campaigns that consider anti-Zionism antisemitic aim to shift criticisms of the Israeli government "beyond the pale of mainstream acceptability". In December 2023, antisemitism expert
David Feldman said that, while "some anti-Zionism takes an antisemitic form", the context must be considered when differentiating antisemitism from legitimate discourse and that there is "a long history of Israel and its supporters portraying anti-Zionism and other criticisms of Israel as antisemitic" to delegitimize them. , under the direction of
Jonathan Greenblatt, who has said "anti-Zionism is antisemitism", has been accused of exploiting the accusation of antisemitism to silence criticism of Israel. In the 2020s, some authors have accused the ADL of advancing false claims of antisemitism against anti-Zionists. Political scientist
Omar Shahabudin McDoom wrote in 2024 that the identification of "critic[ism] of the conduct of the Israeli government" with antisemitism is not necessarily in bad faith but may be attributed to conscious or unconscious "prosemitic" bias: "Although it has long been argued the antisemite label has been used instrumentally to silence critics of Israel, it may not always be disingenuous behaviour." In 2024,
Marshall Ganz accused the
Brandeis Center of
McCarthyism in its responses to critics of Israeli policies as antisemites. In a 2026 editorial in
Critical Research on Religion,
Warren S. Goldstein of the
Center for Critical Research on Religion wrote, "the conflation of being critical of Israel and being antisemitic is an attempt to deflect criticism of the policies of the state of Israel and instead displaces blame on to all Jews" and "it is the poor unhumanitarian behavior of Israel which is the prime driver of antisemitism." In April 2025, American children's educator
Ms. Rachel, who has advocated for children experiencing trauma and starvation in Gaza, featured in an "Antisemite of the Week" column by the pro-Israel advocacy group
StopAntisemitism, which accused her of spreading Hamas propaganda. In November 2025, the group named her a finalist for its "Antisemite of the Year". The left-wing group
Jews for Racial and Economic Justice defended Ms. Rachel, saying that StopAntisemitism "solely exists to punish and harass private and public individuals who criticize the actions of the State of Israel or simply express sympathy for and solidarity with Palestinians."
Jewish anti-Zionism In 1989, Noam Chomsky sarcastically said, "it is now necessary to identify criticism of Israeli policies as anti-Semitism—or in the case of Jews, as 'self-hatred,' so that all possible cases are covered". In 2014, Matthew Abraham wrote, "the traditional response to [anti-Zionist Jews who counter the notion that anti-Zionism is antisemitic] has been to label anti-Zionist Jews as '
self-hating Jews,' which requires a suspension of rationality and sound judgement." During the
Gaza war, scholar
Raz Segal, former
Hillel executive director for
Harvard University Bernie Steinberg, and former Israeli negotiator
Daniel Levy said that antisemitism has been weaponized to silence pro-Palestinian voices, especially in regard to Israel's human rights abuses. According to
Mitchel Plitnick and
Sahar Aziz, a presumption that all Muslims are antisemitic has been "increasingly deployed by Zionist groups to eliminate critical debate inclusive of Palestinian experiences". In 2024, a group of Germanophone scholars said the weaponization of antisemitism against pro-Palestinian protesters, people of color, and post- and decolonial scholars by universities and the Austrian political right meant the "recent increase of antisemitic crimes and the structural antisemitism across Austrian society are thereby obscured". Canary Mission's published materials were called a
blacklist by freelance journalist Alex Kane in
The Intercept, and
James Bamford wrote in
The Nation that Canary Mission weaponizes antisemitism to silence criticism of Israel. In the U.S., Democrats and Republicans have characterized campus
protests in solidarity with the Palestinians in Gaza as "rampant antisemitism", a characterization Israeli Holocaust historian
Raz Segal has called "woefully misguided—and dangerous". Segal, former Hillel Harvard director Bernie Steinberg, and
Jewish Currents editor-in-chief
Arielle Angel said that criticisms of the protests included weaponized antisemitism. Of the
2024 pro-Palestinian protests on university campuses, Segal wrote, "the blanket assertion [of "rampant antisemitism" at the protests] by pro-Israel advocates is intended as a political cudgel: weaponizing antisemitism to shield Israel from criticism of its attack on Gaza". Angel said the American right has weaponized claims of antisemitism against pro-Palestinian campus activism to ban boycotts of Israel and curtail the
right to protest, and that
Republicans and the Anti-Defamation League have attempted to portray pro-Palestinian student protesters as "terrorists".
Harvard University appointed antisemitism scholar
Derek Penslar to head a task force on the issue. After criticism of Penslar, who had signed an open letter critical of Israel's treatment of Palestinians,
Slate columnist Emily Tamkin said his critics were weaponizing antisemitism. Following restrictions on pro-Palestinian protests at universities, several Jewish organizations, activists, and scholars said the
second Trump administration was using antisemitism as a pretext for anti-democratic and authoritarian actions.
Kenneth S. Stern said the Trump administration was "absolutely weaponizing antisemitism" to curtail "speech we don't like", in "a total assault on the university". Representative
Jerry Nadler said Trump was "weaponizing the real pain American Jews face to advance his desire to wield control". Nadler also criticized cuts to the
Office for Civil Rights, which terminated nearly half its staff, as contradicting Trump's claim to combat antisemitism.
Shaul Magid, a rabbi and Jewish studies scholar, has suggested that Republicans used congressional hearings about antisemitism to attack universities'
diversity, equity and inclusion policies rather than to address campus antisemitism. Lara Deeba and Jessica Winegarb, anthropologists of the Middle East, suggest antisemitism has been weaponized in the U.S. against pro-Palestinian students and university staff in an attempt to "silence pro-Palestinian speech, abolish anti-racist teaching and diversity initiatives, eliminate academic freedom, and question the value of higher education in general". In September 2025, a federal judge ruled against Trump's funding freeze for Harvard University, finding that it was "difficult to conclude anything other than that [the Trump administration] used antisemitism as a smokescreen for a targeted, ideologically-motivated assault on this country's premier universities, and did so in a way that runs afoul of [federal law]". Between January and June 2025, nine U.S. attorneys at the U.S. Department of Justice resigned because of the pressure they felt from the Trump administration to conclude that
University of California (UC) campuses had violated the civil rights of Jewish students and staff.
Middle East Monitor reported that Ejaz Baluch, a trial attorney assigned the task of finding antisemitism at the
University of California, Los Angeles (UCLA) called the exercise "unserious": "It was not about trying to find out what really happened", he added. A federal judge found that the Trump administration's proposed settlement with UC was "coercive and retaliatory" and likely violated the
First Amendment. Daniel Ian Rubin and Mara Grayson criticized the
University of California, Santa Cruz Critical Race and Ethnic Studies department's statement following the
October 7 attacks for not condemning the attacks and instead decrying supposed "underhanded efforts" by Jewish nonprofits to "smear" the department's Institute for the Critical Study of Zionism as antisemitic. Rubin and Grayson analyzed the statement as preemptively deflecting accusations of antisemitism by "declaring that any such accusation is strategically designed and unscrupulously deployed to silence criticism of Israel", reinforcing antisemitic tropes about conspiracy and Jewish dishonesty.
International law disputes In February 2022, when
Amnesty International reported that Israel was committing
apartheid in Israel and the Occupied Palestinian Territories, Israel rejected the findings and denounced them as antisemitic. Amnesty secretary general
Agnes Callamard called the Israeli officials' responses "baseless attacks, barefaced lies, fabrications on the messenger". Human rights advocates subsequently argued that the criticism of the report constituted weaponization of antisemitism. During the
Gaza war, pro-Israel advocates, including speakers, writers, and politicians, were accused of weaponizing antisemitism to silence valid
criticism of Israel. Political scientist
Omar Shahabudin McDoom has written that accusations of antisemitism play two roles in what he calls
Gaza genocide denial: claiming that Israel is unfairly targeted in an orchestrated campaign motivated by antisemitism, and attacking the motivations of critics of Israel's genocide.
Martin Shaw has written that Israel's supporters use the ideology of
anti-antisemitism as institutionalized in the U.S., Germany, and other Western countries to block recognition of the genocide. When the
International Criminal Court (ICC) was rumored to be preparing
arrest warrants for Israeli officials, including Prime minister Benjamin Netanyahu,
Aryeh Neier said that Netanyahu's assertion "that ICC indictments would be antisemitic is indicative of his promiscuous use of antisemitism allegations". Shortly thereafter, on 20 May 2024, the ICC announced that it was seeking arrest warrants against Israeli leaders, and Netanyahu called chief prosecutor
Karim Ahmad Khan one of the "great antisemites in modern times", saying that Khan was "callously pouring gasoline on the fires of antisemitism that are raging across the world".
Kenneth Roth said Netanyahu's response was a "common last resort for defenders of Israel" that endangered Jews: "if people see the charge of antisemitism as a thin cover for Israeli war crimes, it will cheapen the concept at a time when a strong defense is needed." In February 2024, Israeli officials accused the
International Court of Justice of antisemitism following
South Africa's genocide case against Israel.
Anthony Lerman wrote in
Declassified UK that the officials' "weaponised antisemitism to deflect criticism" and that "using past experience of anti-Jewish persecution to neutralise criticism of, and generate sympathy for, the Jewish state [...] is decades old".
The left and the right In a 2021 independent study funded by the office of the UK Government's Independent Adviser on Antisemitism (
Lord Mann), academics Daniel Allington and Tanvi Joshi found that alternative media outlets, including
The Skwawkbox and
The Canary on the left and
Tommy Robinson's
TR News on the right, often represent Jews and Zionists as raising antisemitism in bad faith. A 2024 study by the French
Foundation for Political Innovation found that "those close to [left-wing party]
La France Insoumise criticize what they perceive as an abusive use of the accusation of anti-Semitism, which they believe is aimed at muzzling criticism of the Israeli government", giving as an example party founder
Jean-Luc Mélenchon's references to the "paralyzing radius of anti-Semitism" and "genuflections" before the
Representative Council of French Jewish Institutions in French politics. Camilla Brenni et al. criticize the French left for ignoring and minimizing antisemitism, and the radical left in particular for never discussing antisemitism except as an issue tactically instrumentalized against the movement. They write that the left's defensive posture against the supposed "blackmail" of antisemitism prevents any reflection on tropes that infuse antisemitism in both the
sovereigntist left and the nationalist right.
Political right The
German far-right has accused Jews of "using the " () in relation to
new antisemitism,
nationalism, and
neo-Nazism.
German studies scholar Caroline Pearce describes the phrase as a "common far-right term" in contemporary German politics. In 1967, Jewish writer Moshe Menuhin wrote in the German far-right publication
National-Zeitung that antisemitism charges were "becoming more and more a weapon of propaganda serving Zionist aims". During the 1984–1985 trial of
James Keegstra for promoting hatred against Jews, Keegstra told the court that antisemitism was, in the words of
Alan T. Davies, "a smear word invented by Jews to obscure their conspiratorial activities" and "divert public attention from the truth." Upon resigning from the far-right National Front party (now
National Rally) in 2011,
Jean-Marie Le Pen said, "Jews cry wolf, unduly claiming to be victims of anti-Semitism", and that a journalist who had claimed he was racially insulted and violently expelled from a party meeting "could say that it was because he was Jewish that he had been expelled... It could not be seen, neither on his card nor on his nose, if I dare say." The party's next leader, his daughter
Marine Le Pen, said the claim of antisemitism was a lie. French comedian
Dieudonné included in his 2010 show
Mahmoud (named for Iranian president
Mahmoud Ahmadinejad) a sketch in which he complains of "the blackmail of antisemitism" after being called antisemitic by a Jewish character depicted as racist and neurotic. Scholars Stephen W. Sawyer and Roman Zinigrad interpret this sketch as an attempt to spread antisemitic material beyond the far right, intended to appeal to leftists and descendants of immigrants in France. Right-wing American political commentators
Candace Owens and
Tucker Carlson have claimed that accusations of antisemitism are used to silence people, with Owens complaining of "ultimately Marxist [...]
D.C. Jews" raising allegations of antisemitism and Jew-hatred "not because they believed that what they were hearing was actually antisemitism or Jew-hating, but to basically silence people." Owens said separately that Charlie Kirk and Elon Musk have been victims of weaponized claims of antisemitism. During an interview with
Theo Von, Carlson denied being an antisemite and said he was being labeled a Nazi in order to silence his opinions. American
neo-Nazi and former
grand wizard of the Ku Klux Klan David Duke has alleged that the charge of antisemitism is generally a smear used by Zionists in an effort to silence political speech. In 2007, Duke wrote: "It is perfectly acceptable to criticize any nation on the earth for its errors and wrongs, but lo and behold, don't you dare criticize Israel; for if you do that, you will be accused of the most abominable sin in the modern world, the unforgivable sin of anti-Semitism!" He said in 2015 that Jeremy Corbyn was elected leader of the UK Labour Party "despite a massive smear campaign by Britain's Zio-establishment over his association with anti-Zionist activists." A Labour spokesperson told
The Times that Corbyn "obviously" rejects Duke. Duke also praised Roger Waters after German police investigated Waters for allegations of antisemitism. He encouraged Waters, who he said was being attacked "for daring to expose Israel's crimes and the crimes of the Jewish-controlled US government and media", to go further in rejecting of the charge of antisemitism by asserting that "antisemitism is nothing more of vile smear against anyone who dares to expose the UltraRacist Jewish globalists behind both the Palestinian Nakba but also the insane Ukraine war". In 2010, Waters said that the charge of antisemitism is "a screen [the ADL] hides behind" after the ADL said an animation displayed during Waters's tour, showing a bomber plane dropping
stars of David beside dollar signs, had "crossed the line into anti-Semitism". In 2014, two authors of an open letter in
The Lancet accusing Israel of manufacturing a pretext to massacre Gazans endorsed a video by Duke titled "CNN Goldman Sachs & the Zio Matrix".
The Lancet editor-in-chief
Richard Horton declined to retract the letter, calling the revelations "utterly irrelevant" and a "smear campaign". In a 2022 opinion piece,
Spokesperson of the Government of Hungary Zoltán Kovács denied American diplomat
Ira Forman's claims that Hungarian president
Viktor Orbán is antisemitic, and decried "attempt[s] to play the tired antisemitism card over and over again [...] because this charge of antisemitism is a political tool that disregards the facts to push an agenda that has no democratic legitimacy."
Opposition to immigration Several commentators have suggested that political groups on the
populist right and far-right weaponize antisemitism to demonize immigrants, especially Muslims, and obscure their own antisemitism. Political scientist Jelena Subotić suggests that parties such as the
AfD and
Fidesz first declare support for Israel and
Benjamin Netanyahu, then portray their "hostility to Islam and Muslim immigration to Europe" as defending European Jews, as a "shield" from their own antisemitism. She describes this as part of a growing "
pro-Israel antisemitism". Similar criticisms have been made about Austrian politics and academia by
Author Collective scăpa شاه. In 2019, the German
Bundestag passed resolutions declaring the
Boycott, Divestment and Sanctions (BDS) movement antisemitic and compared it to the 1933
Nazi boycott of Jewish businesses. This comparison—and the belief that BDS is "nothing less than the start of a road to another Holocaust"—is prevalent in German discourse. 240 Jewish and Israeli intellectuals, including some specialised in antisemitism and Holocaust research, wrote an open letter criticizing the resolution. Signatories included
Alon Confino,
Amos Goldberg, and
Avi Shlaim. The letter said: We conclude that the rise in anti-Semitism is clearly not the concern which inspired the motion adopted by the Bundestag. On the contrary, this motion is driven by political interests and policies of Israel’s most right-wing government in history.For years, the Israeli government under Prime Minister Benjamin Netanyahu has been labelling any opposition to its illegal and peace-undermining policies as anti-Semitic. No one can be surprised that Netanyahu warmly welcomed the motion by the Bundestag. This embrace illustrates how the fight against anti-Semitism is being instrumentalized to shield policies of the Israeli government that cause severe violations of human rights and that destroy the chances for peace. Commenting on German anti-antisemitism,
Esther Bejarano wrote that criticism of Israel's policies is not antisemitism, and that "I did not survive the Auschwitz extermination camp, the Ravensbrück concentration camp and the death march, to be insulted as an 'anti-Semite'."
IHRA working definition of antisemitism The IHRA definition of antisemitism is the "non-legally binding working definition of antisemitism" that the
International Holocaust Remembrance Alliance (IHRA) adopted in 2016. It was first published in 2005 by the
European Monitoring Centre on Racism and Xenophobia (EUMC), a
European Union agency. Accompanying the working definition are 11 illustrative examples, seven of which relate to
criticism of Israel, that the IHRA describes as guiding its work on antisemitism. In 2011, the UK's
University and College Union Congress debated a motion to formally reject the IHRA's working definition of antisemitism. Antisemitism scholar
David Hirsh said the definition was "denounced as a bad-faith attempt to say that criticism of Israel was antisemitic". In 2019, 2024, and 2025,
Kenneth S. Stern, the lead author of the original definition, said it had become weaponized by Donald Trump and right-wing Jewish groups in ways that threatened to suppress and limit free speech in the U.S. Stern said Trump's
Executive Order on Combating Anti-Semitism, aimed at university campuses in particular, would "harm not only pro-Palestinian advocates, but also Jewish students and faculty, and the academy itself". A 2023 report by the
British Society for Middle Eastern Studies analyzed 40 cases where UK university staff and/or students were accused of antisemitism on the basis of the IHRA definition between 2017 and 2022, and found that in 38 cases, the accusations were dismissed, with two yet to be resolved. According to the report, false accusations of antisemitism have caused staff and students severe stress. In 2023, Middle East scholar
Nathan J. Brown and Israeli academic and peace activist Daniel Nerenberg wrote in
+972 Magazine that the definition, though created in good faith, had been weaponized by groups including the
Zionist Organization of America, the
American Jewish Committee, and the
Brandeis Center. In 2024, Holocaust scholar
Raz Segal wrote: "The weaponization of antisemitism by Israel and its allies, including the U.S. government, draws on the deeply problematic 'working definition of antisemitism' adopted in 2016 by the International Holocaust Remembrance Alliance (IHRA)." Philosopher Eve Garrard countered the idea that the IHRA definition suppresses free speech critical of Israel, writing that the IHRA definition and examples are "peppered with conditional verbs", which Garrard attributes to an adherence to necessary caution in discussions of racism. "The only view which this definition threatens", she wrote, "is the view that criticism of Israel can never, ever, in any circumstances, be antisemitic. But this is not a view which is even remotely plausible (although some critics of the IHRA definition do seem to find it attractive)." Responding to widespread criticism that the definition classifies legitimate speech on Israel as antisemitic, philosopher Bernard Harrison and legal scholar Lesley Klaff argued that such criticism was unfounded.
UK Labour Party In 2018, in light of accusations of
antisemitism in the British Labour Party under
Jeremy Corbyn's leadership,
Communities Secretary Sajid Javid called a debate on antisemitism in Parliament. At the debate, Jewish Labour MPs
Luciana Berger and
Ruth Smeeth spoke of their experiences of being accused of weaponizing antisemitism. Lesley Klaff says Berger experienced online antisemitic and misogynistic harassment by supporters of
Jeremy Corbyn who saw her "as deliberately
manufacturing a crisis within the Labour Party by making false accusations about antisemitism".
Anthony Lerman said that "many hyperbolic claims" were made against Corbyn himself and that such claims "politicized antisemitism" and emptied the word of utility.
Ronnie Kasrils, writing in
Palestine Chronicle, compared the charges to a
witch hunt and to rhetorical strategies against the
South-African anti-apartheid movement. A 2018 YouGov poll of paying Labour members found that 77% believed that the "extent [of the issue of antisemitism] is being deliberately exaggerated to damage Labour and Jeremy Corbyn or to stifle criticism of Israel". Support for Labour among British Jews fell to 13% during the affair. In 2020, the
Equality and Human Rights Commission investigated claims of antisemitism in the UK Labour Party, concluding that investigators should treat complaints of antisemitism in good faith according to the
Macpherson principle, and that dismissing reports of antisemitism without investigation could itself be antisemitic. It said party agents who suggested complaints of antisemitism were "fake or smears" could be guilty of "unlawful harassment". It also said that Jewish members, in particular, were accused of trying to "undermine the Labour Party" with reports of antisemitism, and that this "ignores legitimate and genuine complaints of antisemitism in the Party". In response to the report, several formal complaints were filed against Labour MPs. The
Jewish Labour Movement said, "We were told that this racism was imagined, fabricated for factional advantage or intended to silence debate. Today's report confirms that our voices were marginalised and our members victimised". Gideon Falter, leader of the
Campaign Against Antisemitism, said that the EHRC report "utterly vindicates Britain's Jews who were accused of lying and exaggerating, acting as agents of another country and using their religion to 'smear' the Labour party". Similarly, the Antisemitism Policy Trust's 2020 report on antisemitism in the Labour Party said that some Labour activists had "dismissed [Anti-Jewish hatred] as a 'smear' or as being 'weaponised' by its victims for political ends", which they said was against the Macpherson principle and not supported by the evidence. In 2022, Corbyn's successor as Labour leader,
Keir Starmer, commissioned the
Forde Report, which said antisemitism had been used as a "factional weapon" between the party's anti-Corbyn and pro-Corbyn factions. Michael S. Broschowitz writes that Labour leadership responded to the controversy using a pattern of
DARVO tactics: "denying the antisemitic character of documented incidents by reframing them as 'legitimate criticism of Israel,' attacking complainants as politically motivated actors seeking to 'weaponize antisemitism allegations,' and ultimately reversing victim-offender relationships by characterizing Jewish members raising concerns as the primary threat to party unity and progressive values." According to
Dave Rich, Labour's worldview "made it possible for antisemitic ideas to be expressed and defended as legitimate political discourse, while Jewish concerns about antisemitism were dismissed as attempts to silence criticism." Of the Labour affair,
Howard Jacobson wrote: "That Jews invoke anti-Semitism primarily to silence critics of Israel is a tired
canard, but it continues to be pressed in to service. It serves a purpose: It libels the Jews as liars in the act of protesting innocence of any such offense." Balazs Berkovits wrote that defenders of the Corbyn left throughout the scandal employed rhetoric similar to French discourse about a supposed "state
philosemitism", according to which "Jewish middle and upper classes willingly identify and collude with power elites [and attack] left-wing and working-class Jews." According to Berkovits, this idea "strives to legitimize attacks and critiques conducted against Jews [...] as
something that is just targeting power elites", by first asserting that "power elites, Jews included, attack left-wingers with the antisemitism smear, [such that] the concept of antisemitism is hollowed out, instrumentalized in an absurd fashion, and turned into its opposite." == Responses ==
