They were shifting the balance of power in the Middle East until President Trump got out of this deal, he said adding that the policy of the administration is to make sure that Iran never gets close to a deliverable nuclear weapon.
The implications of the US withdrawal are multi-faceted.
Iran's foreign minister has held talks in China as he began a diplomatic tour with the remaining signatories of a multinational nuclear deal following the recent USA withdrawal from the landmark 2015 pact.
A poll on Channel 2 television the day after Trump scrapped the Iran deal showed Netanyahu's right-wing Likud party would gain five seats if elections were held now, winning 35 in the 120-seat parliament and strengthening its position in a ruling coalition.
It was widely believed to have been a successful piece of global diplomacy at the time, but Trump repeatedly referred to the deal as being the "worst ever" during his election rallies, pointing out that it made no mention of the Iranian ballistic program or the overall influence Iran exerted in the Middle East. But Bolton left open the possibility that if they do not, the U.S. might sanction foreign corporations that continue to do business with Iran.
Europeans are going to face the effect of US sanctions already really because much of what they'd like to sell to Iran involves US technology for which the licenses will not be available, US National Security Advisor John Bolton said.
At the same time, the government said it has tasked the president of the Atomic Energy Organization of Iran with "taking all necessary steps in preparation for Iran to pursue industrial-scale enrichment without any restrictions".
Fellow signatories to the deal have been quick to denounce Trump's decision.
"Do we want to be vassals who obey decisions taken by the United States while clinging to the hem of their pants?"
The U.S. decision reignited the danger of economic crisis for Iran, which is now at the center of Tehran's diplomatic efforts. "It's a U.N. Security Council Resolution and it belongs to the entire world", said Mogherini, who will chair talks Tuesday with the British, French, German and Iranian foreign ministers in Brussels.

This was part of the flaw of the deal to entice Europe and the United States into economic relations with Iran that eventually would have worked against really holding Iran accountable for violations of the deal.
