That is part of a flurry of diplomatic activity lined up following Tuesday's unilateral withdrawal from what US President Donald Trump called "a awful, one-sided deal", a move accompanied by the threat of penalties against any foreign firms doing business in Iran. "It depends on the behavior of other governments".
During a phone call on Friday, Theresa May, UK's Prime Minister said she was "firmly committed to ensuring the deal was upheld, as its the best way of preventing Iran from developing a nuclear weapon", Xinhua News agency reported quoting Downing Street spokesperson.
Part of the flaw with the Iran deal that President Donald Trump rejected was it enticed Europe and the US into economic relations with Iran that would work against holding the country accountable for violations of the agreement, Bolton said.
White House national security adviser John Bolton said United States sanctions on European companies that maintain business dealings with Iran were "possible".
Fuel is expected to rise to $3 per litre following President Donald Trump's decision to pull out of the Iran nuclear deal. And while the decision to withdraw in such a flagrant manner-by reimplementing the nuclear sanctions in place before the start of the agreement-may have been egged on by some of his more hawkish advisors, it is critical to recall that the president is largely following through on a campaign promise to shred the deal.
Iranian hardliners - who have long opposed President Hassan Rouhani's moves to improve ties with the West - are already mobilising against the efforts to save the nuclear deal. It may be tempting for presidents to wield their executive power to their fullest to enact an agenda, but Trump is providing a vivid illustration of the risk of this strategy.
Trump has frequently voiced his opposition to the "insane" deal, which he has described as the "worst ever".
Le Maire said Paris was seeking U.S. waivers and longer transition periods over Iran for French companies including Renault and Total, while pressing for European Union measures to improve the bloc's "economic sovereignty" in the longer term. They were trying to take over the Middle East by whatever means necessary.
Asked whether or not European countries could face such sanctions, Bolton responded: "It's possible".
Then there was amateur-fiction-writer-turned-professional-fiction-writer Ben Rhodes, a former Obama national security aide, who tweeted, "One tragicomic element of Trump's presidency is that the more he tries to tear down Obama's legacy, the bigger he makes Obama look".
European Union foreign policy chief Federica Mogherini insisted that it's not up to the U.S.to determine the deal's future anyway.
As a private citizen, Bolton in the past has suggested that the United States push for a change in Iran's government.
In the CNN interview, Bolton did not respond directly when asked whether Trump might seek "regime change" in Iran, or whether the U.S. military would be ordered to make a preemptive strike against any Iranian nuclear facility.
No regime loyalists would dare say it, especially to an American reporter, but Iranians are furious with their own government's failure to deliver basics like electricity, water and decent wages.
The two leaders agreed for their teams to hold discussions on the potential impact of United States sanctions on firms doing business in Iran.
Inbar said, "Israel has been nurturing the Americans for years..., helping Trump to reach this position".
