Kind of confusing cause and effect a little bit there. It would be like blaming the storm chasers for the big tornado in Missouri last week.
Or crediting Obama for killing Bin Laden. 
I am reluctant to give political leaders the credit or the blame for these military operations, except to the degree that they actually called the shots on the thing.
So Obama gets a small part of the credit for making the final decision to give the mission a green light. Of course the military gets the lion's share of the credit for the execution, so to speak, of the operation.
I give George W Bush a larger share of the credit/blame for the war against Iraq because it was Bush and his people who pushed for the war, the military was not clamoring for such a war on their own, the desire for it came mostly from the political sphere, which at the time was Bush and his Cabinet. The stunning victory of the US military against the Iraqis is all on the military. The politicians didn't defeat Saddam's army, the US military did that.

This follows ancient Roman law. Scientists, like any seer, are subject to the same beheadings that threaten any King or Manor Lord. Otherwise the seers will get lazy and predict things haphazardly. Many have mysteriously disappeared for this reason. Watch as the the teeth chatter on Italian TV weathermen now.
