Iraq War criticism Klein has written about the
Iraq War. In "Baghdad Year Zero" (''
Harper's Magazine, September 2004), Klein argues that, contrary to popular belief, the George W. Bush administration did
have a clear plan for post-invasion Iraq: to build a completely unconstrained free market economy. She describes plans to allow foreigners to extract wealth from Iraq and the methods used to achieve those goals. Her "Baghdad Year Zero" was one of the inspirations for the 2008 film War, Inc.'' Klein's "Bring Najaf to New York" (
The Nation, August 2004) argued that
Muqtada Al Sadr's
Mahdi Army "represents the overwhelmingly mainstream sentiment in Iraq" and that, if he were elected, "Sadr would try to turn Iraq into a
theocracy like Iran," although his immediate demands were for "direct elections and an end to foreign occupation".
Venezuela Klein signed a 2004 petition titled "We would vote for
Hugo Chávez". Rather, according to Klein, Chávez protected his country from financial crisis by building "a zone of relative economic calm and predictability." According to reviewer
Todd Gitlin, who described the overall argument of Klein's book
The Shock Doctrine (2007) as "more right than wrong," Klein is "a romantic," who expected that the Chávez government would produce a bright future in which worker-controlled co-operatives would run the economy.
The Shock Doctrine was consistent with her prior thinking about
globalization, and in that book she describes Chávez' policies as an example of public control of some sectors of the economy as protecting poor people from harm caused by globalization. In 2017, Mark Milke and conservative writer
James Kirchick criticized Klein for her support of Chávez.
Criticism of Israel In 2008, Klein was the keynote speaker at the first national conference of the Alliance of Concerned Jewish Canadians (now
Independent Jewish Voices). In January 2009, during the
Gaza War, Klein supported the
Boycott, Divestment and Sanctions (BDS) campaign against
Israel, arguing that "the best strategy to end the increasingly bloody occupation is for Israel to become the target of the kind of global movement that put an end to apartheid in South Africa." In 2009, on the occasion of the publication of the
Hebrew translation of her book
The Shock Doctrine, Klein visited Israel, the
West Bank, and
Gaza, combining the promotion of her book and the BDS campaign. In an interview with the Israeli newspaper
Haaretz, she emphasized that it was important "not to boycott Israelis but rather to boycott the normalization of Israel and the conflict." In a speech in
Ramallah on June 27, she apologized to
Palestinians for not joining the BDS campaign earlier. Her remarks, particularly that "[some Jews] even think we get one get-away-with-genocide-free card" were characterized by Noam Schimmel, an op-ed columnist in
The Jerusalem Post, as "violent" and "unethical", and as the "most perverse of aspersions on Jews, an age-old stereotype of Jews as intrinsically evil and malicious." Klein was also a spokesperson for the protest against the
spotlight on Tel Aviv at the
2009 Toronto International Film Festival, a spotlight that Klein said was a very selective and misleading portrait of Israel. She has also served on the advisory board of the organization
Jewish Voice for Peace. In 2023, in the context of the
Gaza war, she wrote: At a “Seder in the Streets" event in 2024, held near Senator
Chuck Schumer's residence, Klein spoke about the contemporary meaning of
Passover and its relation to the war. Using
The Exodus story of
Israelites worshipping the
golden calf as an idol, she drew parallels to what she called "the false idol of Zionism." She said "It is a false idol that takes our most profound biblical stories of justice and emancipation from slavery, the story of Passover itself, and turns them into brutalist weapons of colonial land theft, roadmaps for ethnic cleansing and genocide."
Environmentalism By 2009, Klein's attention had turned to environmentalism, with particular focus on
climate change, the subject of her book
This Changes Everything (2014). According to her website in 2016, the book and its accompanying film (released in 2015) would be about "how the
climate crisis can spur economic and political transformation." She served on the board of directors of the non-profit group
350.org from 2011, through the fiscal year ending September 2018, and took part in their "Do the Math" tour in 2013, encouraging a divestment movement. In an interview by Graeme Greene in
New Internationalist, Klein rejected criticism that
This Changes Everything politicized the climate issue and that the issue should be apolitical, asserting that such criticism reflected "how blind so many within the mainstream climate discussion are to the fact that they themselves are fully immersed within the confines of neoliberalism; ... Its a fantasy that you could fundamentally shift the building blocks of your economy without engaging with politics." She encouraged the
Occupy movement to join forces with the environmental movement, saying the financial crisis and the climate crisis are similarly rooted in unrestrained corporate greed. She gave a speech at
Occupy Wall Street where she described the world as "upside down", where we act as if "there is no end to what is actually finite—fossil fuels and the atmospheric space to absorb their emissions," and as if there are "limits to what is actually bountiful—the financial resources to build the kind of society we need." She has been a particularly vocal critic of the
Athabasca oil sands in Alberta, describing it in a
TED talk as a form of "terrestrial skinning." On September 2, 2011, she attended the demonstration against the
Keystone XL pipeline outside the White House and was arrested. Klein celebrated Obama's decision to postpone a decision on the
Keystone pipeline until 2013 pending an environmental review as a victory for the environmental movement. and described her own country, Canada, as a "climate criminal." She presented the Angry Mermaid Award (a satirical award designed to recognize the corporations who have best sabotaged the climate negotiations) to
Monsanto. Writing in the wake of
Hurricane Sandy, she warned that the climate crisis constitutes a massive opportunity for disaster capitalists and corporations seeking to profit from crisis. But equally, the climate crisis "can be a historic moment to usher in the next great wave of progressive change," or a so-called "People's Shock." In 2016, following the election of
Donald Trump as the 45th
President of the United States, Klein called for an international campaign to impose economic sanctions on the United States if his administration refuses to abide by the terms of the
Paris Agreement. In October 2022, Klein published an article on
The Intercept that addressed
COP27 and the repression of the Egyptian government; the conference took place in Egypt, a country widely seen as repressive and autocratic. She goes on to state "
Sisi's Egypt is making a big show of solar panels and biodegradable straws ... but in reality, the regime imprisons activists and bans research. The climate movement should not play along," calling it
greenwashing. In an interview with
Democracy Now!, she says “what is not welcome would be pointing out this enormous lucrative network of deals that the military itself is engaged in that are linked to fossil fuels, that are linked to destroying remaining green space in cities like Cairo”. Klein also stressed the release of prominent political prisoner and activist
Alaa Abd El-Fattah, and wrote a foreword to
You Have Not Yet Been Defeated (2021), his collected writings translated by an anonymous collective.
