WASHINGTON (REUTERS) - The United States on Sunday (May 13) threatened to impose sanctions on European companies that do business with Iran, as the remaining participants in the Iran nuclear accord stiffened their resolve to keep that agreement operational.
White House National Security adviser John Bolton said US sanctions on European companies that maintain business dealings with Iran were "possible," but Secretary of State Mike Pompeo said he remained hopeful Washington and its allies could strike a new nuclear deal with Tehran.
Bolton struck a more hawkish tone with his comments in an interview with CNN's State of the Union programme than Pompeo did when he was interviewed on Fox News Sunday.
US President Donald Trump on May 8 announced that the United States was withdrawing from a 2015 deal negotiated by the Obama administration.
So far, China, France, Russia, Britain, the European Union and Iran remain in the accord, which placed controls on Iran's nuclear programme and led to a relaxation of US economic sanctions against Iran and companies doing business there.
Despite the US exit, Britain and Iran on Sunday expressed their commitment to ensuring that the accord is upheld, according to a statement released by British Prime Minister Theresa May's office.
And Germany said it will spend the next few months trying to persuade Washington to change its mind.
When asked whether the United States might impose sanctions on European companies that continue to do business with Iran, Bolton told CNN: "It's possible. It depends on the conduct of other governments."
Pompeo said he was "hopeful in the days and weeks ahead we can come up with a deal that really works, that really protects the world from Iranian bad behaviour, not just their nuclear programme, but their missiles and their malign behaviour as well."
The US withdrawal from the Iran deal has upset Washington's European allies, cast uncertainty over global oil supplies and raised the risk of conflict in the Middle East.
Germany's minister for economic affairs, Peter Altmaier, said on Sunday that Berlin will try to "persuade the US government to change its behaviour."
In an interview with ZDF public television, Altmaier noted the United States has set a 90-day deadline for foreign firms to comply with the return of sanctions and that this period can be used to convince Washington to change course.
Israel and Iran engaged in an extensive military exchange on the heels of Trump's decision to leave the deal.
On Saturday (May 12), French President Emmanuel Macron told Trump in a telephone call that he was worried about stability in the Middle East, according to Macron's office.
As a private citizen, Bolton in the past has suggested that the United States push for a change in Iran's government.
But in an interview aired on the ABC's This Week programme, Bolton said, "That's not the policy of the administration. The policy of the administration is to make sure that Iran never gets close to deliverable nuclear weapons."
In the CNN interview, Bolton did not respond directly when asked whether Trump might seek "regime change" in Iran, or whether the US military would be ordered to make a preemptive strike against any Iranian nuclear facility.
"I'm not the national security decision-maker," Bolton said, adding that Trump "makes the decision and the advice that I give him is between us."
When pressed by CNN on whether the Trump administration would sanction European firms that continue to do business with Iran, Bolton said, "I think the Europeans will see that it's in their interest ultimately to come along with us."
Bolton said Europe was still digesting Trump's May 8 move.
"I think at the moment there's some feeling in Europe - they're really surprised we got out of it, really surprised at the reimposition of strict sanctions. I think that will sink in; we'll see what happens then," Bolton said.
