I know the gut wrenching, sinking feeling of watching your son head off to the military not knowing what may come of it. My son enlisted in the Army and we figured he'd be in Bosnia. While he did work in support of the action there, luckily he was not in hostile action.
My Dad (rip) told me he felt the same when I left in '65.
The debate over the war is not even a factor when your child leaves to be in harm's way among his brothers in arms.
I wish the best for you and yours.
