When Ronald Reagan turned his back on the neoconservatives, fired them, and had some of them prosecuted, his administration was free of their evil influence, and President Reagan negotiated the end of the Cold War with Soviet President Gorbachev. The military/security complex, the CIA, and the neocons were very much against ending the Cold War as their budgets, power, and ideology were threatened by the prospect of peace between the two nuclear superpowers.
I know about this, because I was part of it. I helped Reagan create the economic base for bringing the threat of a new arms race to a failing Soviet economy in order to pressure the Soviets into agreement to end the Cold War, and I was appointed to a secret presidential committee with subpeona power over the CIA. The secret committee was authorized by President Reagan to evaluate the CIA’s claim that the Soviets would prevail in an arms race. The secret committee concluded that this was the CIA’s way of perpetuting the Cold War and the CIA’s importance.
