A Princeton professor told Pat Roberston in an interview that the United States must destroy terror group Islamic State of Iraq and the Levant (ISIL or ISIS) in Iraq, or risk an attack on U.S. soil.
"We're going to have to fight them somewhere," declared Dr. Robert P. George, McCormick Professor of Jurisprudence at Princeton University.
"Do we want to fight them in New York? Or in Washington, D.C.? Or should we fight them and defeat them in Iraq?"
George called ISIL's ideology "a kind of fanaticism that means they cannot be negotiated with", and warned "We would be fools to stop short of anything but the destruction of this military force."
"They mean to carry out terrorist attacks in Europe and in the United States," said George. "These people do not idly threaten."
George began a petition to destroy ISIL which nearly 12,000 people have signed.
