Kendal, my lad, you are a talented fellow and funny, too boot, but you are, perhaps, allowing your politics to alter your historical perspective. American involvement in WWI was, entirely, within the Wilson administration. The US was involved in WWII long before Pearl Harbor, long before the Axis attacked us. Korea was the UN and the president was Truman. There was a war in Indo China, under Ike, but the French were fighting it.
I'm not suggesting that the Democrats are the party of death and, surely, the two Iraq adventures are pure GOP. It's a crap shoot.
I think that we defend our positions in pre Vietnam wars by avoiding them (The French and Indian War, the Mexican War, The Spanish-American War), trivializing them (WWI, Graneda, Panama) or accepting them as just wars (The Revolutionary War, the Civil War, WWII).
That WWII thing sure makes it tough to come off anti-war, doesn't it?
