As the United Nations wrapped up its latest mission to Tehran and talks on the Middle Eastern country's nuclear programs faltered, the Republican presidential candidates tussled over who would do a better job than Barack Obama in reining in what they said is a rogue Iran. Newt Gingrich said that Iran’s leaders cannot be trusted, saying he would consider a preemptive strike against Iran if he thought Israel’s sovereignty and safety were threatened. Mitt Romney condemned Obama for not pursuing further sanctions against the Islamic Republic. Ron Paul called the hawks “risky and reckless,” and argued for talks, not sanctions and military action. Rick Santorum said Obama is “afraid to stand up to Iran.” When they came down to it, none of the candidates called for intervention in Syria. Apparently, they think Obama has not called on Assad to step down.
