According to Anne Hessing Cahn (Arms Control and Disarmament Agency, 1977–1980), Team B's analysis of weapons systems was later proven to be false. "I would say that all of it was fantasy. ... if you go through most of Team B's specific allegations about weapons systems, and you just examine them one by one, they were all wrong." The CIA director at the time, George H. W. Bush, concluded that the Team B approach set "in motion a process that lends itself to manipulation for purposes other than estimative accuracy." Brookings Institution Scholar Raymond Garthoff concurred, writing that in "retrospect, and with the Team B report and records now largely declassified, it is possible to see that virtually all of Team B's criticisms... proved to be wrong. On several important specific points it wrongly criticized and 'corrected' the official estimates, always in the direction of enlarging the impression of danger and threat." A top CIA analyst called Team B "a kangaroo court of outside critics all picked from one point of view."
