From a former Army brat and an Army wife with a son currently in the Army, I can tell you that it is always hardest for those of us left behind. While we fret and worry, our loved ones are learning to be men/women who learn leadership, brother/sister-hood and accept responsibility not only for themselves but for their fellow soldiers. And if it came to pass that our country really was in peril, I wouldn't hesitate to give my trust to them.
I was on the streets and picket lines protesting Vietnam (and believe me, this Iraq business smells quite familiar)...at the same time my father was serving there. I may have hated the war, but I've never had anything but sincere admiration and respect for those who were sent there. God bless.
