Pre-WWI we were an isolationist country, until the Lusitannia(sp.?) got torp'd. Then after that war we returned to an isolationist point of view. The League of Nations appeased Japan and Germany. So Japan ran rough-shod over Manchuria, and Hitler began his world conquest bid by overrunning Chec. and Poland. After WWII though we realized we couldn't turn a blind eye to world events, so we got involved. Maintained our military might which we had built up during the last war, and when N. K. invaded S.K. we, and the UN, were able to repulse them. Then came Vietnam, because the politicians faught that one instead of leaving it primarily to the generals, we got our heads handed to us.
My point here is that there are always gonna be some small-minded salamanders who want to rule the world. Isolationist views won't keep us out of the conflict, and in fact it allows the conflicts to escalate to world-class proportions. Stay involved, maintain our military strength, and go into any conflict with clear goals in mind and go in to win, no matter what. And let everyone know that, and if they don't like it, they can at least stay out of the way.
