Is European Unity on Iran Nuclear Deal Starting to Crack? Henry Ridgwell LONDON - There are signs that cracks are beginning to appear in European unity over its backing of the 2015 Iran nuclear deal, or JCPOA, as allies come under growing pressure from the United States to abandon the agreement in the wake of Tehran's downing of a passenger jet January8. The 2015 deal, signed by Iran, the U.S., Britain, France, Germany, Russia and China, lifted most sanctions on Iran in return for strict limits on nuclear fuel enrichment. U.S. President Donald Trump withdrew from the deal and reimposed sanctions in 2018, citing concerns about Iran's missile program.
