We're at war with his organization. He's participated in murder and attempts at destroying the U.S. He's a traitor, a murderer, and military target. His U.S. citizenship doesn't make him a special snowflake.

I don't want the U.S. killing non-citizen innocents, I don't want the U.S. killing citizen innocents.

This guy is neither and I don't see how where he was born gives him more special privilege than Osama.
