Diplomats from countries supportive of the deal and opponents of the U.S. have argued that because the United States left the deal in 2018, it now can no longer use mechanisms within the Iran deal.

“Having withdrawn from the JCPoA, the U.S. is no longer a JCPoA participant and therefore ineligible to demand the Security Council invoke a snapback,” Chinese Ambassador Zhang Jun said in a statement after the vote.

The administration, and Cruz, argue against that, saying the U.S. retains rights under the resolution.

“UNSCR 2231 reserves the right of any original participants of the Iran deal to invoke the snapback mechanism, which it explicitly defines as including the United States,” Cruz wrote in an op-ed for Newsweek referring to the U.N. resolution. “How could it not? The entire point of the snapback was to protect the U.S. if Iran exploited the deal to endanger Americans.”

“Having exhausted every other measure to stop Iran from receiving billions of dollars of weapons starting in October, the Trump administration is going back to the UN to put an end to the benefits Iran is receiving from the Iran deal,” he argues. “We can go there tomorrow to begin the process, we should do so and, very soon, we will do so.”

Russian President Vladimir Putin has called for a meeting of leaders of the five permanent Security Council members, along with Germany and Iran, in what the Kremlin has described as an effort to avoid escalation.

While the U.S. has expressed an openness to talks, officials have indicated that it could invoke the snapback mechanism as early as this week.
