Pentagon Spokesman John Allen on ISIS: 'I Think We Are in This For A Matter of Years'

The United States and its allies are steeling themselves for what an American defense official described Thursday as a years long fight against the so-called Islamic State, a revelation that came as airstrikes pummeled oil refineries in Syria used by the terror group to help fund its operations

"I think we are in this for a matter of years," Pentagon spokesman Rear Adm. John Kirby told CNN on Thursday. "... We are steeling ourselves for that period of time."

U.S.-led airstrikes hit locations overnight in a remote area of eastern Syria where ISIS has been using mobile refineries to produce oil that brings in up to $2 million a day for the group.

How much are strikes costing taxpayers?
The U.S. military was still assessing the damage to the refineries by the airstrikes, Kirby said. The attacks are focused on the "infrastructure around the refineries," meaning the ability of ISIS to produce oil, he said.
