LOL, were you asleep when Reagan armed the Contra's, the mujaheddin, retook Grenada, etc
Additionally, Reagan formulated his Diplomacy, and implemented it, late in his Presidency, during his best days as an International Statesman after he learned the best approach to resolve international conflict and Make America Great.
The Soviets were Communists, yes Reagan fought Communism everywhere,and he managed to do it without a Nuclear War. Are you seriously going to tell me that Putin and Russia are still Communist?
