ISIL (ISIS)--or just the Islamic State that straddles Syria and Iraq--now claims to be the leader of the jihad that fights in the name of all Moslems (whether you agree or not).
Which shows that all the focus on defeating core al Qaeda while downplaying the Long War on Islamism was a mistake.
Did we defeat al Qaeda?
Yes.
Does that defeat of the main group to fight us matter now that ISIL might take over jihadi leadership after we ignored their rise on the odd notion that only core al Qaeda counted as a jihadi enemy?
Obviously not. Osama bin Laden as fish food notwithstanding.
