President Donald Trump signed a presidential memorandum Tuesday withdrawing from the Iran nuclear deal. The deal was negotiated and entered into in July 2015 with the aim of reducing Iran’s ability to develop a mass nuclear weapons program.

Here’s a look at the history of the agreement.

Iran, the United States, France, Britain, Germany, Russia and China — after 17 days of negotiations in Vienna — agree to the “Joint Comprehensive Plan of Action.” Under the JCPOA, commonly referred to as the Iran deal, Iran agrees to reduce its nuclear facilities; in return, the other nations agree to lift economic sanctions.
