What bothers me is that there is just 'us' and 'them'. There is not even the hint of allies or any shade of gray in all this, you are either part of the United States or you are fair game.
They are but they're not supposed to be. At least, they weren't. I know that's apparently changed but that is a funny thing to have such a flap over, if you feel that it is somehow bad in principle to target your own civilians when they have not (yet) done anything wrong what is it that makes it a-ok to do the same on foreigners? I can't follow that reasoning.
