BRUSSELS      -    European Union foreign ministers on Monday debated ways to keep the Iran nuclear deal intact after the Islamic Republic began enrichment work at its Fordo site in a fresh act of defiance that seems likely to spell the end of the painstakingly crafted international agreement.

At talks in Brussels, the EU powers that signed the 2015 Iran nuclear deal — Britain, France and Germany — were expected to signal what action should be taken as the bloc awaits a new report from the International Atomic Energy Agency later Monday on whether Iran is still complying with its commitments.

“We want to preserve the (deal), but Iran must finally return to its commitments and comply with them, otherwise we will reserve the right to use all mechanisms that are set out in the agreement,” said German Foreign Minister Heiko Maas.

The EU sees the nuclear pact as a key component of regional and global security and has struggled to stop the nuclear deal from unraveling since President Donald Trump unilaterally pulled the United States out of it over a year ago, triggering debilitating economic sanctions against Iran.

“It’s a great agreement and we need to keep it alive,” Slovakia’s foreign minister, MiroslavLajcak, told reporters. But it remains unclear what more the EU can do as Iran’s economy buckles under the weight of the sanctions, apart from renewing its appeals for restraint and dialogue.

The Europeans have poured a lot of cash and credibility into ensuring the Iran nuclear deal stays afloat. A safeguard was built to keep money flowing to Tehran, but it has not been effective. A system is in place to protect European companies doing business in Iran from U.S. sanctions, even though many remain reluctant because they fear being shut out of the more lucrative American market if they do.

One option could be to trigger the dispute mechanism in the agreement, which would open a window of up to 30 days to resolve the problem. Some are even calling on the Europeans to impose their own sanctions on Iran.

“Sanctions, sanctions, sanctions. We’re not going to solve the problem like that,” said Luxembourg Foreign Minister Jean Asselborn. “Right now, we should wait for the report from the IAEA to see where we stand.”

Dutch Foreign Minister Stef Blok said he was “very worried about Iran’s behavior,” after uranium gas was injected into centrifuges at Fordo last Thursday to produce low-enriched uranium to fuel nuclear power plants. Under the deal, Tehran was not supposed to do this at the site until 2030.

However, the Europeans are hardly surprised by Iran’s actions.

They believe the writing has been on the wall ever since Trump withdrew from the nuclear agreement last year, claiming that it does not to stop Tehran from developing missiles or undermining stability in the Gulf region.
