A Diminished Tehran Talks to Washington

More than six years after pulling the US out of the Joint Comprehensive Plan of Action (JCPOA)—the Iranian nuclear deal—during his first term as president, Donald Trump has signaled that he intends to finalize an understanding aimed at blocking Tehran's nuclear ambitions.

JCPOA was finalized in 2015 by the US, the UK, France, Russia, Germany, and China; and European powers made several half-hearted attempts to revive the deal over the past four years. Trump's decision to pull out of the deal also forced India to stop purchases of Iranian crude because of the threat of secondary sanctions.
