You're the one implying that their deaths don't mean anything, or hadn't you noticed?
Hell, their deaths matter more than almost all the rest. People die in car accidents, of heart attacks, of slipping in the shower, or choking on a hot dog. Their spouses grieve no less, their children are no less bereaved. Were their deaths meaningful? Are most deaths meaningful?
The soldiers in Iraq and Afghanistan are dying to try to free millions of people from tyranny. That's something. Even if they fail, the effort is a noble one.
Funeral for Marine Lance Cpl. Jeramy Ailes in Gilroy. An insurgent playing dead apparently shot him.
