Osama and Al Qaeda are proving to be too tough to the so-called greatest power on Earth. This is being proved both in Iraq and Afghanistan. Defeat is staring America in the face in both these places. Wishing for Osama's death is quite natural :-) But anyway, even this calculation by US is flawed because even if Osama dies there are several next rung leaders who will take over Al Qaeda and run it just as efficiently.
