We were talking about Eastern Europe being dominated by the Soviets, not Asia. So when I said there was less blood and destruction during the Cold War, I was referring to the Iron Curtain countries of Eastern Europe, not what went on inside either China or the Soviet Union. That stuff (Cultural Revolution and Gulag) would've happened anyway, unless you were planning for the U.S. to take on half the world (USSR and China) just after spending 4 years at war with Germany and Japan.
(BTW, it's not often spoken of, but Truman actually did send 50,000 Marines into China in the late 40s when things began to look bleak for Chiang's Nationalist forces. It wasn't nearly enough to stem the tide. The masses supported Mao and the rest is history. Now the "Communist" Chinese have found a way to beat us at our own game: capitalism!)
