Didn't see the story about the parents..
My take- I don't think 100% of the young men and women join the army wanting to go off and fight a war. You see interviews with soldiers where the reporter asks the soldiers what they are doing in Iraq, and they hesitate, then answer "just doing what I'm told. Taking care of business."
I'd wager that if people enlisting in the past were told, "hey, in 2 years you'll be in the middle of Iraq with a high possiblity of dying (not for our freedom necessarily, but for that of the Iraqi people).. Do you still want to enlist? Sure, we'll pay for your school and stuff." that they would say, "hey.. I don't think this is for me."
