Answer by taking a quote from the following article:

Richard Edgar Pipes (born July 11, 1923) is a Polish-American academic who specializes in Russian history, particularly with respect to the Soviet Union, who espoused a strong anti-communist point of view throughout his career. In 1976 he headed Team B, a team of analysts organized by the Central Intelligence Agency who analyzed the strategic capacities and goals of the Soviet military and political leadership. Pipes is the father of American historian and expert on American foreign policy and the Middle East, Daniel Pipes. Pipes was born to a Jewish family in Cieszyn, Poland, which fled the country as refugees after it was invaded by Nazi Germany.

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.

Did they convince people that the Soviet strategy was different?
Pipes maintained that Team B contributed to creating more realistic defense estimates.
