France has warned of a “serious crisis” if agreement is not reached in Vienna within days over reviving the 2015 Iran nuclear deal.

Foreign Minister Jean-Yves Le Drian told the Senate Wednesday that a “tipping point” had been reached. “It's not a matter of weeks, it's a matter of days,” he said. “Political decisions are needed from the Iranians. Either they trigger a serious crisis in the coming days… or they accept an agreement that respects the interests of all the parties.”

Le Drian told the senate that France and other world powers – China, Germany, Russia, the United Kingdom and the United States – were in agreement on the outlines of how to restore the 2015 JCPOA (Joint Comprehensive Plan of Action).

"We are coming to the moment of truth,” he said. “If we want Iran to respect its (nuclear) non-proliferation commitments and in exchange for the United States to lift sanctions, there has to be something left to do it.”

In an interview with the Financial Times published earlier Wednesday, Iran’s Foreign Minister Hossein Amir-Abdollahian suggested the US Congress should issue a “political statement” to reassure Iran it would not again leave the JCPOA, as the US did in 2018.

While the US puts the onus on Iran to reverse steps since 2019 expanding its nuclear program, Iran has argued the US must respect its commitments under the JCPOA, lifting ‘maximum pressure’ sanctions, before it re-joins JCPOA structures.
