The President’s team plan to hit out at the agreement, but stop short of asking Congress to reimpose sanctions which could cause a political fallout.
The 2015 agreement lifted stiff sanctions against Iran that had been in place for decades in exchange for significant restrictions on the nation’s nuclear program.
President Trump called the deal “one of the worst and most one-sided” agreements ever made by the US.
It was signed by Britain, China, the European Union, France, Germany, Iran, Russia and the United States.
The national security team is working with Congress and European allies to put pressure on Iran, but the plans assume a deal will remain in place.

The Donald has until October 15 to certify Iran is complying with the agreement.
If he doesn’t, Congress have 60 days to decide where or reimpose sanctions on Iran that had been suspended under the pact.
Yesterday US Defence Secretary Jim Mattis said it was in the US national interest to stay in the deal.
Speaking to a Senate hearing, Mr Mattis said: “If we can confirm that Iran is living by the agreement, if we can determine that this is in our best interest, then clearly we should stay with it.
”I believe, absent indications to the contrary, it is something that the president should consider staying with.”
An Iran policy expert told Politico: “One of the options [presented to the president] is to decertify, continue to waive the statutory sanctions, slap on new non-nuclear sanctions, roll out a new strategy, and then make the case to the Hill that this is not the time to reinstate the nuclear sanctions and there will be a broader strategy to strengthen the deal.”
President Trump called the deal an “embarrassment to the United States” at the United Nations General Assembly last money, but he has already certified the deal twice this year.
Last month, Iran’s President Hassan Rouhani said the agreement cannot be renegotiated. He said Tehran could abandon its nuclear agreement with world powers “within hours” if the United States imposes any more new sanctions.
Supporters of the agreement say its collapse could trigger a regional arms race, worsen Middle East tensions and discourage countries like North Korea from trusting Washington to keep its word.
European ambassadors speaking in Washington last week said they would do everything possible to protect companies based in Europe and that continue to do business with Iran from reimposed US sanctions.
