Osama bin Laden once referring to the United States as a "paper tiger." I assume that is Arabic for "most powerful killing force in the entire universe."
Many worrying signs concerning Pakistan, though. Also, I'm fairly amused that our use of enhanced interrogation techniques and Gitmo detainees apparently helped lead to this day. For those of you who claimed those actions were not in your name, I agree, you can claim no credit in wiping out bin Laden.
Rest in Pieces.
