KeithC, you really have the perspective of the individualist soldier. Not only should the person subscribing keep in the back of his head that the people around him will be affected too, also, he should be aware of the consequences of his enlisting ánd the possible results - including that he goes into military duty and ends up killing someone.
The fact that most of us have nothing to do with the military doesn't mean we can't form an opinion about it. It's like saying no one should have an opinion about anything, because from the eyes of the people that are really involved, we're not involved. Of course we can have an opinion and of course we can raise valid and important questions. I find it quite disturbing anyone would see that different, as even democracy is based on the fact that anyone can have an opinion and everyone can influence decision-making (to a certain extent).
Even though (it appears that) you loved the military, and I know many other Americans who did, I can tell you I know an equal number who hated their time there, or winded up having recurring nightmares or some who even have light cases of PTSD.
Signing up to the military might be a way to get into life, but it can just as well be your way out of life, or into a life that is haunted by nightmares or similar experiences.
But, you're correct, the decision is solely that of the individual, but any sane individual will also calculate in the effects it can potentially have on their own physical and mental health, the effects it can have on beloved ones and the deeds they potentially have to fulfill.
That you were 'lucky' and didn't get sent out into hell itself, doesn't mean another person will be as 'lucky' as you were. Unless you're really dedicated to fighting for your country, I say that given the current circumstances extreme caution is an appropriate thing.
