Some Iranians are blasting Trump's decision to decertify the nuclear deal

Trump has called the Iran deal'the worst deal ever

At some point, the US may determine that diplomacy has a role in managing the North Korean nuclear and missile challenges. That, however, seems unlikely because Congress does not trust this president and really cannot gauge whether the actions would trigger the end of the JCPOA.

On Friday, Trump declared his administration would not certify Iran's compliance with the landmark pact.

In other words, Congress could craft the policy the administration won't, with flexible benchmarks for progress.

The deal, forged by Iran and the U.S., China, France, Germany, Russia, the United Kingdom and the European Union, requires Tehran to reduce its stockpile of enriched "weapons grade" uranium by 98 percent, remove two-thirds of its centrifuges and remove the core of its heavy water reactor. Trump blamed Corker for the Iran deal (though the senator did not support its original passage), and mocked his slight stature. Big elections this weekend in Austria.

Trump's decision to decertify the deal and his outreach effort was met with anger. He also accused Iran of helping North Korea with its weapons programs.

"It's a middle finger to the US's prudent leadership of the international order", says Hussein Banai, a political scientist at the University of Indiana Bloomington who studies the US-Iran relationship. Nor will he certify that the suspension of sanctions undertaken by the US as part of the agreement is justified and in the vital national interest of the US.

Haley added that she feels "every member of the NSC [National Security Council]" works hard to put options on the table for the president, and that they share the common goal of keeping Americans safe. Under President Franklin Roosevelt, it meant forming a diverse, bipartisan cabinet that would present conflicting points of view, allowing the president to draw his own informed conclusions on policy. What is needed is a policy of containment of Iran across the region - including support for the Kurds in northern Iraq and Syria, as well as of other groups and countries that are pushing back against Iran.

They said they share Trump's concerns about Iran's missile program and other regional activities. "And I think that what the president has done is created now space to prevent a very bad deal from materializing and to fix it. Everybody should join forces in doing just that".

"What is the purpose of a deal that, at best, only delays Iran's nuclear capability for a short period of time?" We see what it's doing. It is a conflict that has increasingly burst into the open. American unilateralism now could make forging a common front against Iran much more difficult in the future. "It doesn't mean they can get everything they want, but they can block things that they don't particularly want". Secretary Tillerson has denied the threat, but pointedly did not deny the slur on Trump's intelligence (although his State Department spokeswoman did deny it).

The leaders of Europe's three largest economies directly rebuked Trump's claim that Iran "committed multiple violations of the agreement", noting in their statement that "the International Atomic Energy Agency has repeatedly confirmed Iran's compliance with the [agreement]".

Iran will likely react with harsh language coming from the top, with Supreme Leader Ayatollah Ali Khamenei "leading the charge" in criticizing the U.S. and specifically Trump, "calling him out not only on the strategy but the language that he used".
