Texas GOP Sen. Ted Cruz, a potential 2016 presidential candidate, made clear this weekend his foreign policy strategy for dealing with the militant group Islamic State: “bomb them back to the Stone Age.”

“They want to go back and reject modernity,” he said. “Well, I think we should help them. We ought to bomb them back to the Stone Age.”

Cruz made his remarks Saturday in Dallas at a summit for Americans for Prosperity, the political arm of the billionaire GOP donors Charles and David Koch.
