And the assassination of an American citizen without the involvement of any judicial process at all doesn't undermine American courts? I don't really know what the right answer is here, if, as claimed, it was indeed impossible to capture al-Awlaki safely. But here you are asserting that he was a foreign national. It seems to me that at the very least, that claim deserved judicial review.
