Nobody want's to see any terrorist getting a chanche to do the things they do and they have to be taken out.
but how are you going to decide which people helped and which don't ?
Innocent people are going to get hurt, just like extremist do when they bomb places
If you are dead sure you have got the responsible ones, waste them but if you take out innocent people everybody will jump up and crucify you guys.
I don't see the USA as the bad guys but others do.
