Republican Presidential Candidates Attack Obama's Handling of ISIS at Iowa Forum

Seven candidates criticized the president's policies.

Cruz called for Kerry’s resignation, drawing cheers from the 1,500 in attendance.

Huckabee went a step further, saying Kerry was "only doing the bidding of the person who appointed him."

"I've got a better idea -- instead of getting rid of John Kerry, I’d like Barack Obama to resign if he’s not going to protect America and instead protect the image of Islam," he said.

Rubio continued the criticism, saying the president "hasn't even defined what victory means."

When asked why President Obama hadn't used more aggressive tactics to fight ISIS, including establishing a ground force with Sunni and Kurdish fighters, Rubio replied, "well, he's a bad president."

Santorum referred to the Obama administration's handling of ISIS as "delusional," saying it cost lives in Paris, Mali, and in the United States.

Fiorina said more needed to be done to stop ISIS from gaining territory.

"What we must do is deny ISIS territory and that means we must cut off their supply lines, we must cut off their money," she said.

Paul turned his focus to the three Democrats running for president and a question from their debate last weekend in Des Moines.

"Nobody on the other stage will even call it what it is -- radical Islam," he said.

"In medicine, you know, we anticipate these kinds of things and we have a bunch of protocols already in place, so you already know how to activate the cascade of activities," he said. "You don't really have to sit there and think about what is the first call you are going to make."
