Harvard Law School professor Alan Dershowitz says the U.S.-Iran nuclear arms deal has Iranians "jumping up and down" but has only a 10 percent possibility of success.
"It's not a good deal when you are in a very strong negotiating position and you give up that negotiating position and you allow a victory for the weaker side," Dershowitz told "The Steve Malzberg Show" on Newsmax TV.

"The Iranians are jumping up and down with joy. As far as they can see, they have won an unequivocal victory … They've gotten relief from the sanctions, they're going to now start getting business from China.
"They're going to be able to continue to develop triggers and other mechanisms that will be useful for any nuclear device and what have they given up? They said, well we're not going to do anything more at this point … This sounds to me like the road to North Korea and look what happened to North Korea."
The famed civil-rights lawyer said the trustworthiness of Hassan Rouhani, the seventh and current President of Iran.
"Nobody knows at this point whether this new guy, Rouhani, is actually more than a smiling face. I don't believe that, but it's possible that there are internal arguments going on within the Iranian government and maybe they are moving in a different direction," Dershowitz said.
"We just don't know. The only thing that's certain is that we're uncertain. We're making this gamble in the face of considerable risks. The real question is, do the risks, the positive outcome of the risks, outweigh the negative?
"For Israel, clearly the risks are too great. For the United States they're too great."
Dershowitz said Iran has a long history of terrorism that can't be ignored.
"Remember, the Iranians killed 240-something American Marines. They blew up a Jewish community center in Argentina. They killed diplomats. This is the greatest state sponsor of terrorism in the history of the world," he said.
"If we could stop them from developing a nuclear bomb, turn them away from terrorism the way we did Libya, the way the Ukraine, on its own, did in South Africa, how much better would that be than a military attack or even continuation of sanctions? Diplomacy is better.
"As Churchill said, jaw-jaw is better than war-war. So I'm willing to give them 10 percent, I'm willing to give [the Obama administration] a B in effort, but I have to give them a B- to a C-, depending on grade inflation, in negotiating skills. I don't think this is bad intention, I just think this is dumb."
