So I spent a week on Vietnam, I'm on to Korea now.:) I'm going backwards, I guess!
I found this article on Eisenhower's campaign and the issue of Korea:
"The biggest fact about the Korean war is this: it was never inevitable, it was never inescapable. No fantastic fiat of history decreed that little South Korea—in the summer of 1950—would fatally tempt Communist aggressors as their easiest victim. No demonic destiny decreed that America had to be bled this way in order to keep South Korea free and to keep freedom itself self-respecting.
