It cracks me up when people say that Reagan was a "great communicator" and that he almost single handedly "broke up" the Soviet Union. Both are almost total nonsense. If anyone thinks that the USSR would not have crumbled unless Reagan was president then the one thing they will never have to worry about is teaching world history.
As for the "great communicator" that is mostly just humorous. I submit this Ronald Reagan quote when someone asked him if nuclear war could be limited to tactical weapons. His handlers were not able to take control and this is what the "great communicator" said:
"Well, I would---if they realized that we---again if---if we led them back to that stalemate only because that our retaliatory power, our seconds, or strike at them after our first strike, would be so destructive that they couldn't afford it, that would hold them off."
Maybe that's what really brought down the USSR.
