Trump announced on Friday that the US would keep the pact in place and waive sanctions against Iran for the "last time", in order to secure agreement from the US' European allies to fix its "terrible flaws".
According to Trita Parsi, president of the National Iranian American Council, Trump is not necessarily backing away from his campaign promise to abandon the deal, but is instead attempting to kill it in an indirect way.
Rejecting the allegations that the Europeans did not support Trump's administration because of their economic interests, the deputy foreign minister said "it would be a big mistake to think that Europeans did that for their economic interests".
His last condition required Capitol Hill lawmakers to pass a bill unilaterally incorporating Iran's missile program into the nuclear deal.
"Our worst expectations are coming true", Ryabkov said Saturday.
"Today, I am waiving the application of certain nuclear sanctions, but only in order to secure our European allies' agreement to fix the awful flaws of the Iran nuclear deal".
Officials, congressional aides and outside administration advisers said had the president would likely extend the sanctions waivers, citing progress in amending US legislation that governs Washington's participation in the deal.
The U.S. President Donald Trump once again had to extend waivers that are mandatory under the deal reached between Iran and world powers, officially called the Joint Comprehensive Plan of Action (JCPOA), the Foreign Ministry said in a statement. He also wants Tehran's ballistic missile program to be addressed.
Iran, it said, would not accept any amendments to the nuclear deal "now or in the future" or allow any other issues to be linked to it.
Trump will next have to deal with these decisions in mid-May. JCPOA is not renegotiable: "rather than repeating exhausted rhetoric, U.S. must bring itself into full compliance -just like Iran".
The U.S. agreed to unfreeze tens of billions of dollars of Iran's assets in exchange for the country reducing its number of uranium enrichment centrifuges and shrinking its uranium stockpile by 98%, which Obama said to Mic at the time "prevents Iran from getting a nuclear weapon".
Diplomacy Works, a pressure group set up by former secretary of state John Kerry to defend the deal, was scathing.
Russian Federation yesterday said Washington would be making a grave mistake by pulling out of the Iran nuclear deal, adding that Moscow would work hard to keep the landmark agreement alive.
