Team B was a competitive analysis exercise commissioned by the Central Intelligence Agency in the 1970s to analyze threats the Soviet Union posed to the security of the United States. Team B, approved by then Director of Central Intelligence George H. W. Bush, was composed of "outside experts" who attempted to counter the positions of intelligence officials within the CIA. Team B concluded that the National Intelligence Estimate on the Soviet Union, generated yearly by the CIA, underestimated Soviet military power and misinterpreted Soviet strategic intentions. Its findings were leaked to the press shortly after Jimmy Carter''s 1976 presidential election win in an attempt to appeal to anti-communists in both parties and not appear partisan. The Team B reports became the intellectual foundation for the idea of "the window of vulnerability" and of the massive arms buildup that began toward the end of the Carter administration and accelerated under President Ronald Reagan.
