he served as a member of the National Security Council, holding the post of Director of East European and Soviet Affairs under President Ronald Reagan. He also became head of the Nationalities Working Group. Pipes was a member of the Committee on the Present Danger from 1977 until 1992 and belonged to the Council of Foreign Relations. He also attended two Bilderberg Meetings, at both of which he lectured. In the 1970s, Pipes was a leading critic of détente, which he described as "inspired by intellectual indolence and based on ignorance of one's antagonist and therefore inherently inept". Team B Pipes was head of the 1976 Team B, composed of civilian experts and retired military officers and agreed to by then-CIA director George H.W. Bush at the urging of the president's Foreign Intelligence Advisory Board (PFIAB) as a competitive analysis exercise. Team B was created at the instigation of then Secretary of Defense Donald Rumsfeld as an antagonist force to a group of CIA intelligence officials known as Team A. His hope was that it would produce a much more aggressive assessment of Soviet Union military capabilities. Unsurprisingly, it argued that the National Intelligence Estimate on the Soviet Union, generated yearly by the CIA, underestimated both Soviet military strategy and ambition and misinterpreted Soviet strategic intentions. Team B faced criticism. The international relations journalist Fred Kaplan writes that Team B "turns out to have been wrong on nearly every point." Pipes's group insisted that the Soviet Union, as of 1976, maintained "a large and expanding Gross National Product," and argued that the CIA belief that economic chaos hindered the USSR's defenses was a ruse on the part of the USSR. One CIA employee called Team B "a kangaroo court". Pipes called Team B's evidence "soft." Team B came to the conclusion that the Soviets had developed several new weapons, featuring a nuclear-armed submarine fleet that used a system that did not depend on active sonar, and was thus undetectable by existing technology. According to Pipes, "Team B was appointed to look at the evidence and to see if we could conclude that the actual Soviet strategy is different from ours, i.e. the strategy of Mutual Assured Destruction (MAD). It has now been demonstrated totally that it was". In 1986, Pipes maintained that Team B contributed to creating more realistic defense estimates. Writings on Russian history Pipes wrote many books on
