I nominate Osama bin Hide'n...er...Laden
I would wager he will be dead before the year is out. He desreves the Hitler trophy for suicide since he will go down in the history of the new 21st century as committing suicide by pointing a super power at his head and pulling the trigger. His death will also be one of the most expensive suicides in history. Though on a per/capita basis Hitler still reigns supreme as the committer of the most expensive suicide.
Making more fun of Osama:
Osama is a master of disguises as well as a master of...well... I guess being a cave man.
Currently he is in the guise of Osama bin Hide'n, though he has been spotted as Osama bin Run'n, General Frank suspects he will soon take on the persona of Osama bin Bleed'n followed by Osama bin Die'n. Later on he may apear as Osma bin Rotten and finally, in the future. he will be known as Osama bin Forgotten.
