Today was the first day of the University for Seniors class "Cold War Revisited" led by Neil Storch, a UMD Professor Emeritus. It was supposed to be the second day, but the "Cold War" was cancelled because of the cold (a blizzard).
I'm not a great note taker, but I do get some highlights.
What we know of history today may not be true tomorrow. New evidence seems to become available frequently, especially about recent history. Archives may be opened or other sources may be discovered. For example, the Soviet archives showed that Julius Rosenberg really was a spy.
Much of the Cold War was an attempt to contain the Soviet Union, especially in Europe. There was great concern in the West that Stalin would overrun Europe to expand the Soviet Empire. Stalin didn't want to invade Western Europe because it would reunite Germany, and even under Soviet control, Germany would be a threat to the Soviet Union.
