The resignation of Iraqi Prime Minister Nouri al-Maliki has revived hopes that the Iraqi government can unify the country to battle the growing threat posed by ISIS terrorists.

Krauthammer: Obama's Bluff in Iraq Has Been Called

President Obama has said that the U.S. will continue with limited airstrikes and humanitarian aid, but there will be no troops on the ground, which has led to critics saying the U.S. is not doing enough to help Iraq and prevent the spread of ISIS.

On "Outnumbered" today, Mike Huckabee said the president's decisions are not being made for humanitarian, diplomatic or military purposes, but for political reasons.

"These are tough times where people are being slaughtered like sheep. And you need a shepherd to stop the wolf," he said.

Kirsten Powers agreed with Huckabee that Obama's actions, or lack thereof, are likely politically motivated and pointed to a lack of defined, stated U.S. strategy as evidence of that.

Huckabee said that Obama will try to do as little as possible in Iraq because he doesn't want there to be a military intervention.

"The problem is you're dealing not with a group of terrorists who are just going to do occasional strikes or suicide bombs," Huckabee said. "This is a highly organized, well-financed, out-of-the-box kind of terrorism effort that wants to take control of an entire country, and ultimately region and world."

Huckabee said that ISIS is a cancer that needs to be cut out.

"We're either going to kill the cancer, or the cancer is going to kill us," he said. "We better make the decision who dies. ISIS or freedom?"
