Former New York City Mayor Rudy Giuliani said on "Hannity" tonight that President Obama's disastrous foreign policy is to blame for the rise of ISIS and the deadly terror attacks in Paris.

"This did not have to happen if our policies were different," Giuliani said. "If President Obama had listened to Sen. McCain and Sen. Graham and a whole group of other people, and had set up a no-fly zone in Syria five years ago, if we had gone in and worked with the Syrian legitimate rebels, if we had not taken our troops out of Iraq and Afghanistan, ISIS never would have emerged."

Giuliani explained that ISIS is filling a vacuum, created by the president's "vacuous" foreign policy.

"ISIS is an Obama creation."
