Iran is Obama’s biggest failure, says rival Mitt

Branding Iran's nuclear drive as President Barack Obama's ‘biggest failure’, Republican White House hopeful Mitt Romney has vowed to prevent Tehran from developing atomic weapons if voted to power.

‘Well, I can certainly look at his record and I think one can say that he's had some successes and he's had some failures. And perhaps the biggest failure is as it relates to the greatest threat that America faces and the world faces, which is a nuclear Iran,’ Romney told NBC news in an interview.

‘The President has not drawn us further away from a nuclear Iran. In fact, Iran is closer to having a weapon, closer to having nuclear capability than when he took office. ‘This is the greatest failure, in my opinion, of his foreign policy,’ Romney alleged when asked about the foreign policy of the US President.

‘He ran for office saying he was going to meet with Ahmadinejad. He was going to meet with Castro, Kim Jong-il. All the world's worst actors, without precondition, he'd meet with them in his first year,’ Romney said.

‘The Republican presidential candidate said if voted to power his administration would keep ‘every option that is available to us’ open in order to prevent Iran from developing nuclear weapons. However, Romney did not specify exactly how he would stiffen policy towards the Islamic Republic.
