Tehran — Before Donald Trump has even arrived in the White House, Iran says the US has already violated the nuclear deal and threatened to build nuclear-powered ships in retaliation. Is the historic accord at risk?
Earlier this month, US lawmakers renewed a law called the Iran Sanctions Act, extending its provisions for another decade.
First introduced in 1996, the act aimed to cut off foreign investment in Iran’s oil and gas sector to starve it of funds that might be used for its nuclear programme or to fund "terrorist" groups.
Key provisions of the Iran Sanctions Act were suspended in January when the nuclear deal between Iran and world powers came into force, although Washington has kept others linked to human rights and terrorism in place.
The White House said renewing the act was pointless since it remains suspended so long as Tehran sticks to its promises to curb its nuclear programme.
Knowing it would pass anyway, President Barack Obama let the law through, but refused to sign it.
The president symbolically let slide a deadline to ink his name on the legislation — which he has called unnecessary — meaning the 10-year sanctions renewal will automatically become law.
Even if it were pointless, Tehran was up in arms, with both the supreme leader Ayatollah Ali Khamenei and President Hassan Rouhani calling the renewal a "clear violation" of the accord and lodging a formal complaint with the United Nations.
So is Iran right about a violation? Iran points to article 26 of the deal, which says the US "will refrain from reintroducing or reimposing the sanctions specified in Annex II", which includes the Iran Sanctions Act.
It argues that even if the sanctions remain suspended, the law has still been "reintroduced".
"The US Congress never liked the deal and now that Obama is leaving office, they’re trying to find ways of violating the deal without being too obvious about it," said Foad Izadi, a world politics professor at the University of Tehran.
Western analysts disagree, saying Iran is just trying to score political points.
"If it doesn’t have any practical impact, who cares about the legislation? I think the Iranians are just posturing," said Dan Newcomb, a sanctions lawyer with Shearman and Sterling in New York.
Moreover, sanctions expert Sam Cutler, of consultancy Horizon Client Access, said there was "a zero percent chance" that Iran was not briefed during the nuclear talks that the Congress would reintroduce the Iran Sanctions Act.
"The Iranians knew this was going to happen and for them to claim this is a violation now beggars belief," he said.
A specific phrase was included in the deal — referring to "the respective roles of the president and the Congress" — to draw a dividing line between the actions of the White House and sabotage attempts by hawkish lawmakers, Cutler says.
So if the Iran Sanctions Act is suspended and the renewal makes no difference, why is Tehran making such a fuss? The answer lies with Iran’s wider frustration that the nuclear deal has not produced all of the benefits it had expected, said Izadi.
"Iran is not getting what it thought it would get. The reason Iran is going to the complaints process is not just the Iran Sanctions Act, it is also other areas where the other side has not played its part," he said.
Top of the list are Iran’s continued banking problems. Although hundreds of European companies are desperate to resume trading with Iran, major banks are still refusing to facilitate big transactions.
This is because Washington still has a number of nonnuclear sanctions in place that prevent anyone doing business with a long list of Iranians it says are linked to terrorism, human rights abuses and its ballistic missile programme.
The banks would have to sift through each transaction to make sure none of the money ended up with someone on this list — a costly and time-consuming affair when dealing with a country as opaque as Iran.
A wrong move could result in gigantic penalties such as the $9bn fine slapped on French bank BNP Paribas in 2014.
When the banks ask the US Treasury for guidance, the answers are slow and ambiguous, says Izadi.
"They ask for a green light, and they are given a yellow light, which is not enough."
The problem was than banks had been excluded from the nuclear talks, said Newcomb. "I don’t think either side understood that the financial community would not simply turn 180 degrees on Iran transactions because of this deal."
He tried to explain the problem to both US state department officials and Iranian delegations, but no one listened, he says.
"I think [the Iranians] thought ... if the president announces sanctions are removed, then everything will fall into place. They come from a different political climate."
None of this amounts to a clear breach of the nuclear deal by the US, but the Iranians see it as another attempt to quietly undermine the accord.
As for Iran’s plans to produce nuclear-powered ships, experts say this is not a violation either, or at least not yet.
It was a carefully chosen response by Rouhani because nuclear engines could use highly enriched uranium — also used for nuclear weapons — but not of necessity.
France and China use only low-enriched uranium in their nuclear-powered ships, said Shashank Joshi, from the RUSI think tank in London.
"Iran is showing they’re looking into doing something tough, without actually doing it ... that they’re willing to tear up the deal if pushed too far."
