United Nations crisis looms as United States readies demand for Iran sanctions

After a resounding defeat in the UN Security Council, the United States is poised to call for the United Nations to reimpose sanctions on Iran under a rarely used diplomatic manoeuvre — a move that is likely to further isolate the Trump administration and may set off a credibility crisis for the United Nations.

The sanctions had been eased under the 2015 nuclear deal that President Donald Trump withdrew from two years ago. But last week the US lost its long-shot bid to indefinitely extend an international arms embargo on Iran and has now moved to a new diplomatic line of attack.

US Secretary of State Mike Pompeo is set to travel to New York on Thursday to notify the Security Council president that the United States is invoking the “snapback” mechanism in the council's resolution that endorsed the nuclear deal. It allows participants to demand the restoration of all UN sanctions in a complicated procedure that cannot be blocked by a veto.

The State Department is expected to announce Pompeo's travel plans on Wednesday, but he and Trump have made no secret of their intention to invoke snapback, especially since their attempt to extend the arms embargo suffered an embarrassing defeat last Friday. The US won just one other “yes” vote, with China and Russia opposed and the 11 other members abstaining.

Just like the arms embargo extension, the administration's snapback plan is bitterly opposed by China and Russia as well as the other Security Council members, including US allies Britain and France, and could set the stage for a battle over the legitimacy of the UN's most powerful body.

Alone among the council's 15 members, the US argues that as an original participant in the nuclear deal it retains the right to demand the restoration of sanctions. The others, which still support the deal, maintain the US lost that standing when Trump pulled out of the accord in 2018, but it isn't clear if they can stop the invocation of snapback through technical procedural means.

The US argument is highly controversial. It has been ridiculed by the Chinese, Russians and Europeans, and not even the biggest Iran hawks in the United States all agree with it.

Former Trump national security adviser John Bolton, no slouch when it comes to anti-Iran positions, has long said that the US lost its snapback standing when it withdrew from the deal and that moving ahead is not worth the damage it could do to US veto power in the council.

In a stunningly rare moment of agreement, Iran's Foreign Minister Mohammed Javad Zarif praised Bolton this week. "At least he is consistent — a trait notably absent in this US administration,” Zarif tweeted.

And, former US Undersecretary of State for Political Affairs Wendy Sherman, a top Obama administration negotiator of the nuclear agreement, said: “It was never expected that someone who withdrew from the (deal) would have standing to in fact bring the snapback provision.”

Thus, the administration's insistence on moving ahead has set the stage for a contentious dispute and the possibility that the US call would simply be ignored by other UN members. That outcome would potentially call into question the Security Council's ability to enforce its own legally binding decisions.

Under the terms of Security Council Resolution 2231, which enshrined the nuclear deal and to which the US remains a party, the invocation of snapback for significant Iranian noncompliance starts a 30-day clock during which the council must vote affirmatively to continue the sanctions relief that Iran was given in return for curbs on its nuclear programme.
