it's *they* who are ultimately responsible for collateral damage caused by civilians being too close to the fighting.

You say that you're opposed to this war, but you don't seem to take that into account here. If we weren't there fighting a war that most of the world is opposed to, then US soldiers wouldn't be killing any Iraqi civilians.

It's pointless to lay blame. Noncombatants have been being killed ever since wars stopped being personal fights amongst aristocracy. It sucks, but there's nothing you can do about it.
