Individuals are VERY important. You can find countless examples through history of one person alone rallying others to do some incredible things.
Osama Bin Laden is a very smart man. Do not underestimate him. It is very important that he gets caught, killed, or incapacitated if the US doesnt want more very cohesive terrorist attacks.
They should send a lone super sniper to kill him. A sniper with 2 day face stubble and a 'silent but strong' personality, whose beautiful wife and children all died on a terrorist attack, and he's out on a vengeance.
