Mitt Romney joined Chris Wallace today on Fox News Sunday and took aim at President Obama's "out of touch" foreign policy, criticizing how he has handled Iraq, Russia and the growth of ISIS.

The former GOP candidate also said there is "no question" he would be a better president than Obama or Hillary Clinton, despite the fact he has repeatedly denied he will be running again in 2016.

In an op-ed in The Washington Post last week, Romney wrote, "The history of the 20th century teaches that power-hungry tyrants ultimately feast on the appeasers," critiquing the president's weak foreign policy that calls for relying on "common humanity" with our enemies

"I think the president is really out of touch with reality when it comes to what's happening in the world. I don't know why that is. Perhaps it's his political philosophy or foreign policy views," Romney said, pointing to Obama incorrectly seeing Iraq as stabile, Russia as a potential ally and ISIS as a lowly "JV squad."

Asked by Wallace about the Fox News Reporting special, "13 Hours at Benghazi," which reveals the smoking gun behind the 2012 terror attacks, Romney said it raises many questions about a potential cover-up and the administration's lack of transparency.

"That's something that doesn't just land at the feet of the president. That lands at the feet of Hillary Clinton, as well. She keeps on saying, 'There's nothing to see here. Just move on.' People want to understand exactly what happened."

Wallace noted a recent CNN poll that revealed Romney would defeat Obama in a rematch of the 2012 presidential election and asked if Americans are feeling "buyer's remorse" for electing the current president, but Romney shifted the focus back to Obama's poor track record on foreign policy.

When Wallace asked Romney about his comments that "circumstances can change" regarding a potential White House run in 2016, the former governor of Massachusetts replied, “I’m not running. I’m not planning on running. I’m going to be helping the person who takes the banner for us.”

“Look, there’s no question in my mind that I think I'd have been a better president than Barack Obama has been. No question in my mind about that," Romney said.

"It was a great experience running for president ... but my time has come and gone.”

When Wallace pressed him about if he thinks he would make a better president than Hillary Clinton, Romney replied, “No question about that in my mind.”
