Members of the Red Army Faction Socialist Patients' Collective (SPK) and Movement 2 June (J2M). The SPK, the leftist, 'therapy-through-violence' group, dissolved in 1971, and those members who had turned militant forged links and joined with the Baader-Meinhof Gang. Brigitte Mohnhaupt, Klaus Jünschke Carmen Roll, and Gerhard Müller had already joined as part of the first generation of the RAF but originally started in SPK. Siegfried Hausner (24 January 1952 – 5 May 1975) was a leading member of the SPK especially involved with explosives. He took part in a bombing of the Axel Springer Verlag in 1971 and was the leader of the West German
Red Army Faction politicians (like Richard Nixon and Helmut Schmidt) as well as some former U.S. agents (who were willing to testify) to be called as witnesses. Later when their requests were rejected, U.S. agents Barton Osbourne (ex-CIA, ex-member of the Phoenix Program), G. Peck (NSA), and Gary Thomas gave extensive interviews (organized by defense lawyers) on 23 June 1976 where they explained how FRG support was crucial for U.S. operations in Vietnam. Peck concluded that the RAF "was the response to criminal aggression of the U.S. government in Indochina and the assistance of the German government. The real terrorist was my government."
