1995 Venona decryptions The
Venona project was a United States
counterintelligence program to decrypt messages transmitted by the
intelligence agencies of the Soviet Union. Initiated when the Soviet Union was an ally of the U.S., the program continued during the
Cold War when it was considered an enemy. The Venona messages did not feature in the Rosenbergs' trial, which relied instead on testimony from their collaborators, but they heavily informed the U.S. government's overall approach to investigating and prosecuting domestic communists. In 1995, the U.S. government made public many documents decoded by the Venona project, showing Julius Rosenberg's role as part of a productive ring of spies. For example, a 1944 cable (which gives the name of Ruth Greenglass in clear text) says that Ruth's husband David is being recruited as a spy by his sister (that is, Ethel Rosenberg) and her husband. The cable also makes clear that the sister's husband is involved enough in espionage to have his own codename ("Antenna" and later "Liberal"). Ethel did not have a codename; He said he gave false testimony to protect himself and his wife and that he was encouraged by the prosecution to do so. "My wife is more important to me than my sister. Or my mother or my father, OK? And she was the mother of my children." Numerous articles were published in 2008 related to the Rosenberg case. Deputy Attorney General of the United States
William P. Rogers, who had been part of the prosecution of the Rosenbergs, discussed their strategy at the time in relation to seeking the death sentence for Ethel. He said they had urged the death sentence for Ethel in an effort to extract a full confession from Julius. He reportedly said "she called our bluff" as she made no effort to push her husband to any action.
2008 Morton Sobell's statements (left),
Marshall Perlin,
Robert Meeropol, Franz Loeser, April 19, 1976 In September 2008, Morton Sobell was interviewed by
The New York Times after the revelations from grand jury testimony. He admitted that he had given documents to the Soviet contact but said these had to do with defensive radar and weaponry. He confirmed that Julius Rosenberg was "in a conspiracy that delivered to the Soviets classified military and industrial information... [on] the atomic bomb", and "[Julius] never told me about anything else that he was engaged in." In a
New York Times article, Sobell was paraphrased as saying that he thought the hand-drawn diagrams and other atomic-bomb details acquired by Greenglass and passed to Julius were of "little value" to the Soviet Union and were used only to corroborate what they had learned "from other moles." He also said that he believed Ethel Rosenberg was aware of her husband's deeds but took no part in them.
2009 Vassiliev notebooks based on KGB archives In 2009, extensive notes collected from KGB archives were made public in a book published by Yale University Press:
Spies: The Rise and Fall of the KGB in America, written by
John Earl Haynes,
Harvey Klehr, and Alexander Vassiliev. Vassiliev's notebooks included KGB comments concerning Julius and Ethel Rosenberg, and make clear that the KGB considered Julius Rosenberg an effective agent and Ethel a supporter of his work. According to Vassiliev, Julius and Ethel worked personally with KGB agents who were given the codenames
Twain and
Callistratus, and were described as being the ones who recruited Greenglass and McNutt for the Manhattan Project spy mission. Michael and Robert co-wrote a book about their and their parents' lives,
We Are Your Sons: The Legacy of Ethel and Julius Rosenberg (1975). Robert wrote the memoir ''An Execution in the Family: One Son's Journey'' (2003). In 1990, he founded the
Rosenberg Fund for Children, a nonprofit foundation that provides support for children of targeted liberal activists and youth who are targeted as activists. Michael's daughter
Ivy Meeropol directed a 2004 documentary about her grandparents,
Heir to an Execution, which was featured at the
Sundance Film Festival. Their sons' current position is that Julius was legally guilty of the conspiracy charge, although not of atomic spying, while Ethel was only generally aware of his activities. The children say that their father did not deserve the death penalty and that their mother was wrongly convicted. They continue to campaign for Ethel to be posthumously legally exonerated. In March 2016, Michael and Robert (via the Rosenberg Fund for Children) launched a petition campaign calling on President Obama and U.S. Attorney General
Loretta Lynch to formally exonerate Ethel Rosenberg. In October 2016, both Michael and Robert Meeropol spoke with
Anderson Cooper in an interview which aired on
60 Minutes. In January 2017, Senator
Elizabeth Warren sent Obama a letter requesting consideration of the exoneration request. In 2021, Ethel's sons restarted the campaign to pardon Ethel as they were optimistic that President
Joe Biden would consider this favorably.
Ethel Rosenberg: A Cold War Tragedy by
Anne Sebba was published by Orion Books in 2021. Michael and Robert were requesting Director of National Intelligence
Avril Haines to release the records related to their mother's case, per a 2009 executive order. In 2024, the Meeropols were given a copy of a contemporary hand-written memo by
Meredith Gardner, a linguist and codebreaker at what later became the NSA, based on Russian decrypts. It claimed that Ethel Rosenberg knew about Julius' espionage work but that "due to ill health she did not engage in the work herself". ==Artistic representations==
