Bill Roggio of Long War Journal demurs and I am personally agnostic beyond appreciating the confusion this will sow in al Qaeda until the situation sorts itself out.
If al-Zawahiri is dead I can fill you in on the left's narrative.
He was actually taken prisoner months/years ago and has been held in some secret CIA prison. Now the military has drugged him, taken him to a remote site, and hit him with an airstrike. They did this to help John McCain win the election.
How else do you explain it happening right now? Hmmmm?
