There is not a country in the Middle East worth a single American life, even if there was any provision in law for our soldiers to deployed in these wars. Certainly anyone who wants to go can do so on their own as a volunteer. But these young people are lied to:
“I know there’s a lot of folks out there that might think that suicide is a scapegoat, it’s an escape, and you’re quitting, but when you’re a young person, and you’ve seen the things that we’ve seen, you’ve had to do some of the things that we’ve had to do, it can wear on you,” Place said. “It’s really that invisible wound. And the toughest part is admitting it, admitting that you need help.”
They "had to do" nothing. It's not lack of psychiatry, it is performing acts that cause PTSD that is the problem. In a defensive war there would not be these problems. In an offensive war, it's a whole different ball game.
Bring home the troops now.
