you have some misunderstandingsNo, Article 37 of the JCPOA allows any participant in the agreement (U.S., UK, France, Russia, China, Germany + Iran) to automatically reinstate UN sanctions against Iran if it violates the treaty. However, this only applies if the treaty is still in effect. In August 2020, the U.S. attempted to trigger the mechanism but was ignored by the Security Council because it had withdrawn from the agreement in 2018. Can the remaining members activate the snapback? They could try, as the U.S. did in 2020 (and failed), but it would likely be blocked before even reaching a vote—since the agreement was already violated by the U.S. (which is why the U.S. failed to trigger the snapback in 2020). Even if it passed this initial stage, it would then need full unanimous approval from the UN Security Council. In this case, China and Russia would veto it.
US did not try because it left the deal and was no longer a party, and only a party to JCPOA can invoke snapback
there is no requirement for other parties to not be in violation to invoke snapback
and the vote does not need unanimous approval of UNSC and it cannot be vetoed. in fact, it is the opposite: it needs unanimous approval to NOT be invoked once you pass the first stage.
