If we do something like this, we must do it with care.
Remember that it was thinking like that, that caused us to arm the anti-Russian rebels in Afganistan in the first place.
As for enemies, I'm sure he has boat loads. Remember that the Taliban doesn't control 100% of the area of Afganistan. Part of the north is under the control of warlords opposed to the Taliban and it's allies. I'm sure any of them would be glad to attack bin Ladin.
