Don't forget those that were DRAFTED! There was plenty of anti-war, pacifism, and neutrality seekers then. The idea that the US was galvanized for war against evil is not accurate. Never has been that way. Hopefully we'll never need to be 100% 'for' going to war. That said, it still stinks for the troops. I've watch at least three rotations go home and feel good watching them grow more and more excited as they get short.
In WWII, yes, we did have the draft. Draft dodgers were locked up in prison. Nobody had any doubts about what Hitler would do if given the opportunity to invade the States.
True, but bear in mind that the draft didn't create a big emmigration to Canada or anti-war protests all over the country. Nor did it create a hatred for Presidents Roosevelt or Truman. There will always be people who are opposed to war, but today, (unlike back then), these folks find it necessary to viciously attack our President, try to destroy our military's reputation and morale, and divide and weaken our nation. Because America was more closely knit back then, people just would not get away with this sort of treacherous behavior.
