Who are Iran's nuclear negotiators?

A day after Iran agreed to limit its nuclear program in exchange for lighter economic sanctions, the difference in the moods on the streets of Tehran and Jerusalem couldn't be starker.

"I'm very happy about this agreement," one man told CNN in Tehran. "We hope all the world knows we use this nuclear (power) just for peace, not for war."

With the exception of extreme hard-liners, many Iranians are extremely happy with the deal, especially after many rounds of negotiations that yielded no results.

Iranian newspapers lauded the agreement, with one proclaiming on the front page: "This is Iran, and everyone is happy."

But just across the region in Jerusalem, many residents echoed the sentiments of Israeli Prime Minister Benjamin Netanyahu, who slammed the deal as "a historic mistake."

But how was such a pivotal deal made?
