Speaking as a Vet, I would like to point out that the reason we have troops is not to have them sitting about in CONUS cleaning stuff. We hire them, train them, and equip them, to go out and kill people, blow stuff up, and yes... sometimes get themselves killed in the process. That's why a lot of folks shy away from that line of work.
Crying over some troops getting killed is like crying about NFL players getting injured during a game. Getting yourself injured or killed in combat as a member of the military is part of the job and no secret, and hasn't been since the first group of folks decided to get organized and go kill some other group. It happens, it's the nature of the job, and it's expected that some folks are going to end up dead.
I recognized when I was enlisted that my life was at risk, and that it might be expended in the furtherence of US policy. And after I had a wife, three kids, and a family depending on me, I exercised my option to say my family was more important than the job and I left. I sacrificed a lot of personal freedoms, income, and comfort during that ten years, and I lost several close friends to combat and non-combat related injuries, but like most folks who accepted that same risk, I have no problem with tasking today's military to go and get killed in furthering today's policies.
What Forestal doesn't understand is that no one can cheapen the lives of our service members as our lives are priceless. It is only people who are too afraid for their own personal safety, those who would never lend themselves to sacrifice for their country and feel belittled by those who do, who seek to justify their own outlooks by bringing the troops home and keeping them safe. They want to project their value system of self-worth on those who have a value system of personal sacrifice for the benefit of the whole, which is something the anti-war crowd just do not understand.
