Derek Leebaert, professor of government at Georgetown University, supported Team B in his 2002 book "The Fifty Year Wound: How America's Cold War Victory Shapes Our World". Although he agrees that "Team B's alternative National Intelligence Estimate contained its own mistakes", he claims that "Russian sources now show that the Team B analysts were fundamentally correct on all the key issues." He further says that when Team B and the CIA debated their reports in 1976, the CIA "conceded all essential points on Soviet nuclear war strategy to its harshest critics."
