Iranian President Hassan Rouhani suggested over the weekend that the Republican presidential candidates were so "laughable" that "the people of Iran look at them as a form of entertainment."

"Sometimes when I would have time some of [the Republican presidential debates were] broadcast live and I would watch it," Rouhani told CNN's Christiane Amanpour. "Some of it was quite laughable. It was very strange, the things that they spoke of."

"Some of them wouldn't even know where Tehran was in relation to Iran," the president said with a smile. "Some of them wouldn't know where Iran was geographically, not distinguishing that one is the capital of the other. What they spoke of was quite far away from the truth."

"So, the people of Iran were looking at it as a form of entertainment, if you will, and found it laughable," he added.

Rouhani reminded the candidates the nuclear agreement was not just between the U.S. and Iran, noting that other nations were part of the deal as well.

"Can a government become a signatory to an international agreement and then the subsequent government tear it to shreds?" he asked. "This is something that only the likes of Saddam Hussein would do. So, any government that replaces the current government must keep itself committed to the commitments given by the previous administration."

"Otherwise, that government, that entire country will lose trust internationally," the president concluded.
