Well, they had those spyplanes in the air at the time and apparently it was the unmanned drones that dropped the bombs. Well, this got me thinking...
With all the technology thats around now, why not just activate the nightvision on them (and if they havent got them, well, then theyre fuckin useless), parachute in a few hundred men - dont tell me that they havent got the manpower to do so - and capture him instead? They could get a lot of useful information from that guy, and the guys that are around him. Or, gas the area - Im sure that theyve got gas that can render people unconscious for a coupla hours, and even if it does harm people, they can be in and out before the innocents wake up again and deny all knowledge of such an attack. Yeah, Its a bit unfair, but if he DEFINATELY was there and avoided the attack, and we coulda gassed him and captured him alive, then surely 20 deaths is worth all the information hes holding about stashed WMD's (if any), future attacks etc.
Just my POV.
