Gorby was a Communist through and through.
You did not get to the top of the USSR being a half-hearted Commi.
If the Politburo or KGB knew what the end result would be from his attempts to save Communism... they would have put a bullet in his head.
He tried to save Communism, not bring it down.
Reagan recognized the opening and went full out to use that opening of bankrupting the USSR... and succeeded.
The Soviets admitted it.
Demokrats in America tried to stop Reagan. Their Goebbels Media tried to paint him as an idiot, dangerous, and not in touch with the real world.
Reagan schooled them all. But is seems our American citizens have failed to learn the lessons of history. Not surprising. Ignorance abounds... it's how you get nominees like Obama, Clinton(s) and Sanders. Alinskyites and Socialists.
