Will President-elect Donald Trump crash the Iran deal on day one, as he said on the campaign trail? If so, Barack Obama’s signature foreign policy initiative, the Joint Comprehensive Plan of Action (JCPOA), will melt into air. Obama allies and Iran deal supporters at home and abroad are already showing their anxiety.

The president-elect shouldn’t tear up the agreement, argues the National Iranian American Council, a key voice in the administration’s deal-promoting echo chamber. NIAC’s Reza Marashi and Trita Parsi wrote last week that it’s “in the interest of the United States to build on the Iran nuclear deal to resolve remaining tensions with Iran and help stabilize the Middle East.”
