My gym is owned by former marines, so there are quite a few military folks that train there. The ones I have talked to have been shocked and dismayed at the mis-information about the war and what's really going on. This is even amongst those soldiers who think it was wrong to go over there.
So we should take their word for it? Despite all the proof that's right in front of our eyes that tells us Iraq is a mess? I don't understand your logic here. Remember these are soliders, they sacraficed a lot, so naturally they'll say what they fought for was a great and justified cause. They wont swallow their prides!
I talked to this one Vietnam veteran and I asked him what he thought of the anti-war crowd of that era and he was like "they're communists, they're that" and a bunch of other nonsense. I could have taken this guy's word for it, but I knew what he was spewing was utter nonsense.
