US President Donald Trump softened his rhetoric just days after he threatened Iran "will suffer consequences the likes of which few throughout history have ever suffered before."

The US walked away from the Iran nuclear deal two months ago. Recently at a speech in Kansas City, Missouri, the president declared, “We are ready to make a real deal, not the deal that was done by the previous administration, which was a disaster.”

Trita Parsi, the founder, and president of the National Iranian American Council said compared to nuclear issue in the DPRK, it is more difficult to deal with Iran and pivot the diplomacy despite Trump’s intent to go back to the negotiating table.

“(The) DPRK is a one-man show,” Parsi said. “He has the flexibility of being able to just turn on a dime whereas the Iranian political system, certainly not a democracy, but the power is dispersed within the elite, and it’s very difficult for them to be able to make shifts of this kind without paying a heavy political price.”

Parsi also pointed out that there is a consensus among both Trump’s competitors and allies when it comes to the DPRK nuclear issue. However, in the case of Iran, allies of the United States in the Middle East, such as Saudi Arabia and Israel, have opposed diplomacy and favored military actions.

Michael Johns, co-founder of the National Tea Party Movement, favored the president, saying Trump is fulfilling his campaign promise. He believed the previous deal was flawed in many aspects and the president is trying to fix those problems.

“I think he makes a reasonable point that’s embraced by the American people,” Johns said. “If we’re going to have an agreement with Iran, it should include a legitimate and broad description of how we are going to interact as peaceful nations toward each other.”

However, Eleanor Clift, a political analyst for the Daily Beast, said Trump wants to undo everything his predecessor Barack Obama did, throwing red meat to his base, but like always, he is rarely delivering any concrete plan of action in place.

“Now the grand nuclear agreement had the support of America’s allies, plus Russia and China, and they all want to stay in it,” Clift said. “It had a limited objective, which was a substantial objective to curb the nuclear program. Fine, keep that in place and then get a treaty about ballistic missiles or build it through diplomacy. Instead, this president just chose to walk away from the deal to blow it up.”

Trump’s on-again, off-again attitude has been considered by some people as his negotiating tactic, but Parsi did not think it was a wise move to build up leverage by imposing new sanctions on Iran.

“If Trump truly is interested in diplomacy, this is not the way to do it with Iran,” Parsi said. “That’s the same thing the Obama administration did and what did the Iranians do? They aggressively expanded their nuclear program, so by the time the two sides met at the table, both of them had extensive leverage.”
