Not only did Reagan not end the Cold War...I think the end of the Cold War more or less deprived Reagan of his defining purpose in life....taking on the "Evil Empire" in a final climactic shootout on the streets of "Dodge City"! ;-) He must have felt lost when the Soviet Union collapsed, the enemy vanished, and the gunfight was no longer to be.

He clearly was quite nonplussed when Gorbachev proposed mutual disarmament of all Russian and American nuclear weapons at their summit in Iceland. It wasn't accoring to the script, and he didn't know what to say! He'd have been much happier negotiating with some hardass commie bastard like Joe Stalin or Leonid Brezhnev.
