I think the drone campaign against Al Qaeda is necessary and effective, and I’m not even particularly squeamish about killing Americans who happen to be present at a legitimate military target. But I’m very uncomfortable about deliberately targeting Americans, particularly children:
He was an American boy, born in America. Though he’d lived in Yemen since he was about seven, he was still an American citizen, which should have made it harder for the United States to kill him.
It should at the very least have made it necessary for the United States to say why it killed him.
