Princeton University professor Robert George warned Wednesday that the Islamic State will carry out “mass slaughter in the United States” if it is not soon “destroyed as a fighting force.”

“They have every intention of getting [to the United States], and these are people who achieve what they set out to achieve,” George said on The Glenn Beck Program with guest host Dana Loesch. “Unless somebody stops them, they make good on their threats. They have threatened to carry out activity in the United States — killing people, mass slaughter in the United States.”

“Believe me, I plead with you, I want your listeners to believe me — these people will do it if they can,” George continued. “And they will be able to do it unless we stop them.”

The Princeton professor described the Islamic State as “genocidal,” saying: “They mean to wipe out entire communities, and there is nothing they will stop short of when it comes to achieving their goal.”

“Our well-being, our security, our place in the world are vitally threatened by ISIS and ISIL,” he said. “They will stop at nothing … in order to destroy anyone standing in their way so that they can establish the caliphate.”

George advocated working with the international community to supply air support, as well as strategic and intelligence support, to Kurdish forces, Sunni tribesmen, and other local forces resisting the Islamic State. He also advocated airstrikes against Islamic State strongholds.

George said “we’re going to have to fight them eventually.” The only question is whether we do it in Iraq, or wait “until they’re carrying out terrorist activity within the United States.”
