I'm opposed to all of it.
If it doesn't involve directly defending my own country I won't participate. I don't care whose idea it is, R or D, makes no difference to me.
If we're invaded, I'm going to try to kill the invaders myself. You won't need to draft me. At that point I would see the military as an asset, an ally.
But once you're in you go where they say and do what they say no questions asked. Given our government's track record and desire to be 'global policeman', they haven't earned that trust.
If we had a foreign policy closer to Switzerland, I wouldn't be so opposed.
