Rick Santorum continued the tough rhetoric from Republican presidential candidates on Iran Sunday morning.


When asked by Meet The Press host David Gregory what he would do differently than President Barack Obama towards Tehran, Santorum was adamant in how aggressive he would be.

"I would be saying to the Iranians, you either open those facilities, begin to dismantle them and make them available to inspectors or we will degrade those facilities though air strikes," he said. "And make it very public that we are doing that."

Gregory replied: "So you lay out a red line and if they passed it, air strikes by President Santorum?"

"Iran would not get a nuclear weapon under my watch," he said.
