Since he wants to shrink it to a “manageable problem” and not eliminate it he has lost all claim to be president and should resign at once.
Actions on the scale of what George W. Bush did barely resulted in anything close to reducing jihadism to a "manageable problem." What Zippo did as a follow-up, though he claimed AQ was "on the run" and "decimated", quickly allowed for the escalation we see now as what he calls ISIL.
ISIS is only as powerful as they are through CIA training and copious Benghazi-related arms.
Long and the short, the only kind of "manageable problem" Ohammed has in mind is one where he can talk to ISIS leadership and our mainstream press into "cooling it" and "lying low" so as to make his job of continuing to support them easier.
