If we knew where Bin laden was, and we actually knew it. We would bomb the hell out of it.
OBL is the spiritual leader of AQ.He must be heard by his flock and he has not been heard from.
He never was a planner or a logistic guy. His value was only spiritual leadership and justification.
He could have easily resumed this from a wheel chair or bed, but he has not.
I think the reason is obvious.
