If it had gone wrong, every single person complaining now would be pointing to Obama and saying it was all his fault, and they would be right.
You are projecting your own ignorance. I, for one, would never condemn a leader for a failure, military or otherwise, unless that leader failed to supply all of the support necessary for success.
Nor, do I give the leader credit for success, unless he was fully involved in the planning and logistics of the operation. I give Obama credit for finally finding the guts to OK the operation. That is all the credit he deserves, since others found Bin Laden, laid the plans for his capture or kill, and carried out the operation.
The single fact that Obama considered what a failure would mean to his own political aspirations, detracts from his finding the guts to give the OK. A real man does not consider the personal upside or downside, when others are putting their lives on the line in the operation.
