WASHINGTON (CBSDC) – Former CIA and NSA director Michael Hayden says the United States must step up military efforts in order to defeat the Islamic State of Iraq and Syria.

“What we’re doing right now in Syria and Iraq against ISIS is under-resourced and over-regulated,” he told “CBS This Morning.” “We need to commit more to the fight and we need to loosen our rules of engagement.”

Hayden said airstrikes have been successful in reducing the ability of the Islamic militant group to operate.

“American air power destroyed over a hundred tanker trucks in Syria that were being used to literally fuel the treasury of the Islamic State,” he explained, referring to a recent round of sorties.

But air power alone is not enough, he warns.

“We need Arab allies on the ground, stiffened, assisted and abled by a larger American footprint,” he told “CBS This Morning.”

Hayden says beating ISIS on the ground is crucial to limiting its appeal to other radicalized Muslims.

“This is a fight where the ideological struggle, the motivation, is tightly tied to their success on the battlefield,” he said.

He added it’s unlikely that an American city will see a terror attack similar to what happened in Paris.

“We’re a tougher target because we’re distant; we’re a tougher target because our demographics are different; we’re a tougher target because we’re actually pretty good at this.”
