Cold War?
Aren't you under counting?
Add the Korean War to the Vietnam war casualties and you're already over 100,000.
And then there are all the little battles that were kept secret, like during the Tet Offensive in Vietnam, North Korean commandos came through DMZ and killed a bunch of Marines before being stopped a block from the Presidential palace in Seoul. There was fighting in the mountains with North Koreans for months by our Special Forces till they finally forced another lull.
