With more than 3,200 U.S. military installations on high alert over an unspecified ISIS threat, Gen. David Petraeus (Ret.), former CIA Director, spoke to Maria Bartiromo on "Sunday Morning Futures" about the fight against the terror group.

Petraeus asserted that ISIS has steadily lost ground and has steadily been pushed back in Iraq.

"Getting them on the run is the first step toward the ultimate defeat," Petraeus said.

As for Syria, Petraeus said it's a terrible situation, with thousands of people killed and millions displaced in a conflict that could be called both a religious war and a proxy war.

"You have to wonder if Humpty Dumpty can be put back together again. And that's, I think, going to unfold in the months and years that lie ahead," Petraeus said.

How important is U.S. leadership in the region? Bartiromo asked.

"I think there is very clear recognition that American leadership is not only needed, but that it has to be provided," Petraeus said, noting that the U.S. is indeed leading the coalition against the Islamic State.
