After Trump announced a unilateral decision to stop participation in the deal, Iranian President Hassan Rouhani called the move illegal, illegitimate and a violation of worldwide law, but promised that his country would continue to comply with the deal's conditions despite the U.S. pullout.
Earlier in the day, Iranian President Hassan Rouhani called the decision of USA as "unacceptable".
"I urge Iran to respond to the USA decision with restraint and continue to observe its commitments under the JCPOA", Johnson said.
Both as a candidate and since entering office, the president has derided the deal, arguing it could allow Iran to quickly produce a nuclear bomb once the deal's provisions expire.
Mogherini's remarks followed a statement from US President Donald Trump yesterday announcing his decision to terminate the USA's participation in the Joint Comprehensive Plan of Action (JCPOA), saying it "failed to protect America's national security interests".
Iranians reacted with sadness, resignation and defiance to U.S. President Donald Trump's withdrawal from the nuclear deal.
Lawmakers held the impromptu demonstration the day after Trump's decision.
The FO also reiterated its support for the Iran deal - which had limited Iran's nuclear programme so that the latter could not produce a bomb, in return for the lifting of most of the United States and global sanctions against it.
"Under the current situation, Iran has no commitment whatsoever to be put in a position it was in the past as regards the nuclear issue", Larijani added. Yet, Iranian nation is persistent while former USA presidents passed away & IRI is still standing.
"Iran's exports of oil to Asia and Europe will nearly certainly decline later this year and into 2019 as some nations seek alternatives in order to avoid trouble with Washington and as sanctions start to bite", said Sukrit Vijayakar, director of energy consultancy Trifecta. "If you want to conclude an agreement, obtain real guarantees, otherwise tomorrow they will do the same as the U.S".
"We will wait several weeks before applying this decision".
British Foreign Secretary Boris Johnson told his Parliament that Britain will continue to respect the deal as long as worldwide inspectors can verify Iran's compliance. "If they do there will be very severe consequences".
Menendez needed no convincing to oppose the deal, but agreed with Booker that the USA was better off with a flawed agreement that could be tightened down the road.
"In two years, France has tripled its trade surplus with Iran", he said. Critics and supporters are claiming the others' approach will ultimately let Iran acquire nuclear weapons. However, some analysts have suggested that the nuclear agreement would likely collapse altogether if the US made a decision to pull out.
