(CNN) – Widespread unrest in the Middle East signals a major failure of President Barack Obama's policies in the region, former New York City Mayor Rudy Giuliani asserted Sunday.
The 2008 Republican presidential candidate claimed the so-called "reset" strategy toward the region that was part of Obama's 2008 campaign has proven ineffective and dangerous.

"What we see is the president's policies in the Middle East falling apart," Giuliani told CNN chief political correspondent Candy Crowley on "State of the Union." "I mean, the reality is the president got elected to reset our relationship in the Middle East. We might as well not have had the reset."
A Mitt Romney presidency would do a better job of asserting American interests in the region, Giuliani said, including setting clear "red lines" that Iran should not cross in its nuclear program.
While Israeli leaders have called on the United States to join them in setting the specific threshold that would prompt action against Iran, both Obama and Romney have declined to say exactly what that threshold would be. Both have said it would be unacceptable for Iran to develop a nuclear weapon.
On Sunday, Giuliani said Romney may yet lay out a specific "red line" ahead of November's election.
"I believe that Mitt Romney would set a red line," Giuliani said. Pressed by Crowley on why Romney hasn't set such a boundary already, the former mayor said there was still time for the candidate to spell out his position.
"He might over the course of these debates," Giuliani said. "He might very well do it. Although you'd criticize him for being engaged in foreign policy. Mitt Romney can't win."
The recent spate of protests in the Middle East has triggered a rare detour into foreign policy on the presidential campaign, which until now has been largely focused on the nation's still-struggling economy. Giuliani said that kind of change of focus shows the folly of making assumptions about who will win in November.
"Whoever is overconfident about who is going to win this election is probably going to lose it," Giuliani said. "This is a darn close election. Who ever expected what happened in the last week, week and a half? This was going to be an election about the economy."
