Just think about how much money was saved by ending the Cold War. That was actually driven by government spending. It was also driven by technology (and spending on technology).
Yes, ending the cold war was great. I even give Reagan some credit for it by pushing them over the edge. Seems like we could have gotten the same outcome at a 1/10 the cost.
#2 The cold war ended under reagan as a point of history.
Not sure how much is left to quarrel about?
