[11] He was accused of collaborating with Nazi Germany during the invasion of the Soviet Union's North Caucasus before coming to the United States.
[15]: 1038 [10]: 45 [16][9] Accusations against Soobzokov came to national attention in 1977 with the publication of Howard Blum's exposé of Nazi war criminal residing in the United States, Wanted!
[18] In July 1980, the OSI withdrew its suit after the CIA shared with investigators a copy of Soobzokov's State Department Form V-30, which confirmed his claims he had disclosed service with the North Caucasian Legion and the Waffen SS when applying for his US immigration visa in Amman.
[20][15][9]: 170–174 A trove of classified CIA documents released in 2006 under the Nazi War Crimes Disclosure Act contained admissions by Soobzokov that validated witness testimony taken from survivors in the 1970s, and vindicated Blum's research.
[21][15][22] The first documented evidence of Soobzokov's involvement in war crimes comes from reports made in 1943, after the Nazis had been driven from the North Caucasus.
[15]: 1040–1041 Further testimony gathered in 1976 from surviving Nazi collaborators who had served with Soobzokov confirmed his participation in raids and executions in the auls (villages) of Edepsukai-1, Edepsukai-2, and Dzhidzkhihabl.
[9]: 120 [5]: 149 Circassian immigrants who had known Soobzokov in Paterson claimed that he had bragged about serving in German punitive detachments and participating in executions.

[5]: 160 The Agency sent Soobzokov to Beirut on an assignment to recruit Russian exiles willing to return to the Soviet Union as undercover agents.
The assignment was cut short after the Agency learned that Soobzokov was openly flaunting his CIA affiliation and running a scheme promising to use his connections to help refugees emigrate to America.
[9]: 53–54 Soobzokov had falsely told the CIA that he had attended a Soviet military academy, a claim he later recanted when the Agency decided to send him to a bomb-making course in Fort Meade, Maryland in 1958.
[9]: 55 Finally, after a 1959 debriefing, a CIA examiner concluded that Soobzokov was an "incorrigible fabricator," after which the Agency cancelled his operational approval.
In 1994, Manning was convicted of an unrelated non-political murder, that of computer company secretary Patricia Wilkerson in California, in July 1980, and sentenced to life in prison.
