One other point. A nation's freedom is very much not in the minds of the youngsters who were sent to defend it. Yes, lots of them go into the hell of Muslim World with the correct notion they are trusted by their goverment to promote the cause of freedom. But from the earliest wars, when the real trouble comes to the indiviudal soldier, he wants only to survive. The only thing he wants more than survival is for his friends to survive, and in his precious mind in those heated and terrible moments, that's what it takes. The goverments of the world who send their kids to die are so very much aware of that. Get them in with talk of righteousness, make them hate the enemy, have them believe that their actions will keep their children from oppression, and they will go. But in those last moments, all politics of their country or the grandeur that is America, leaves them as surely as if they'd already been shot. They stay alive to keep their friends alive, but in doing so, they unwittingly keep us free by giving their best.
