The new sanctions will almost certainly anger Iranian officials, but are likely to be cautiously welcomed by the other parties to the JCPOA: the European Union, China, France, Germany, Russia, and the U.K., all of which wanted the deal to be preserved because, they said, it had succeeded in freezing the Islamic Republic’s nuclear program and its uranium-enrichment activity.The Trump administration’s withdrawal from the Paris climate deal and the Trans-Pacific Partnership trade deal, both signature foreign-policy initiatives of President Obama, bolster fears that the JCPOA could go the same way. Trump’s remarks on the presidential campaign trail, where he called the agreement the “worst deal ever,” further cast its future into doubt. But the JCPOA’s other signatories, especially the EU and the U.K., have been vocal in their support of the agreement and have made their case to the White House and lawmakers. China and Russia, who are also parties to the deal, have also signaled they will stay in it.
