Eric Lichtblau: “A secret history of the United States government’s Nazi-hunting operation concludes that American intelligence officials created a “safe haven” in the United States for Nazis and their collaborators after World War II, and it details decades of clashes, often hidden, with other nations over war criminals here and abroad. The 600-page report, which the Justice Department has tried to keep secret for four years, provides new evidence about more than two dozen of the most notorious Nazi cases of the last three decades. It describes the government’s posthumous pursuit of Dr. Josef Mengele, the so-called Angel of Death at Auschwitz, part of whose scalp was kept in a Justice Department official’s drawer; the vigilante killing of a former Waffen SS soldier in New Jersey; and the government’s mistaken identification of the Treblinka concentration camp guard known as Ivan the Terrible. The report catalogs both the successes and failures of the band of lawyers, historians and investigators at the Justice Department’s Office of Special Investigations, which was created in 1979 to deport Nazis. Perhaps the report’s most damning disclosures come in assessing the Central Intelligence Agency’s involvement with Nazi émigrés. Scholars and previous government reports had acknowledged the C.I.A.’s use of Nazis for postwar intelligence purposes. But this report goes further in documenting the level of American complicity and deception in such operations. The Justice Department report, describing what it calls “the government’s collaboration with persecutors,” says that O.S.I investigators learned that some of the Nazis “were indeed knowingly granted entry” to the United States, even though government officials were aware of their pasts. “America, which prided itself on being a safe haven for the persecuted, became — in some small measure — a safe haven for persecutors as well,” it said. The report also documents divisions within the government over the effort and the legal pitfalls in relying on testimony from Holocaust survivors that was decades old. The report also concluded that the number of Nazis who made it into the United States was almost certainly much smaller than 10,000, the figure widely cited by government officials. The Justice Department has resisted making the report public since 2006. Under the threat of a lawsuit, it turned over a heavily redacted version last month to a private research group, the National Security Archive, but even then many of the most legally and diplomatically sensitive portions were omitted. A complete version was obtained by The New York Times.”
