Of particular note:

Reagan didn't end the cold war. Gorbachev did. The USSR collapsed mostly from internal economic and social pressure from decades of Cold-war militarization and posturing against the Europeans and Americans. Even the CIA, which was dedicated to bringing about the downfall of the Soviet Union, admitted surprise that the Soviets disbanded and democratized all by themselves.

An ultra-rightist here, with too much time on his hands? Perhaps. He has some good points, but some mis-informed ones, too. Bush's push in Afghanistan severely weakened the power-base of Al-Quaeda, yes, but the invasion of Iraq just gave them a new place to set up shop, and a new breeding ground for future terrorists.
