The Iran nuclear deal is (not quite) dead. Long live the Iran nuclear deal (maybe).

After dubbing the 2015 nuclear pact the Obama administration and five other world powers inked with Tehran as the “the worst deal ever,” President Donald Trump on Friday will announce he is keeping the United States in the agreement. For now, at least.

“The intent is that we will stay in the JCPOA,” Secretary of State Rex Tillerson told reporters Thursday evening at the White House, using shorthand for the Iran pact’s formal name: Joint Comprehensive Plan of Action. “But the president is going to decertify” the pact, he added.

Trump’s decertification decision is rife with the kind of Washington insider bureaucratic jujitsu he harshly derided as a candidate and has continued to criticize as president. His move comes not within the actual framework of the seven-country agreement, but under a U.S. law passed in 2015 by lawmakers who were skeptical of the deal and eager to exercise oversight.

That means, for now, the Obama administration’s deal remains in place.
