Although the agreement may have begun as a series of discussions, the Iran Nuclear Agreement Review Act of 2015 („Review Act”) has reformulated the type of agreement in the Iran agreement. What was originally intended to be an opportunity to limit presidential power could have been exactly what would have turned „a constitutionally dubious exercise of a unilateral executive branch (a „single executive agreement”) into a constitutionally infallible exercise of the common legislative and executive branch (an „executive agreement of Congress”). Ultimately, it was this review act that gave President Obama the power to „conclude a legally binding nuclear deal, not just an informal political pact.” In addition to the „constitutional text, democratic principles and deeply entrenched practice,” the revision law passed in May 2015 supports the binding nature of the agreement and „gives the government the power to negotiate and implement binding legal commitments with Iran.” But can the Iran deal meet the challenge of the next U.S. government? Can the next president dissolve the agreement in a legal and unilateral way? In 2015, during his election campaign, Donald Trump called the Iran deal a „disaster” and „the worst deal ever negotiated.” It is not unlikely that the new government, despite calls from all parties not to back down, will look for ways to quickly withdraw from the agreement or abolish it. But can President Trump legally dissolve the agreement or is he bound to abide by his terms? This contribution suggests that, although President Trump has the power to legally dismantle the agreement (both as an international matter and as a domestic policy matter), it would be extremely unwise to do so. On July 18, Obama dedicated his weekly radio address to the agreement, saying, „This agreement will make America and the world safer and safer,” refuting „a lot of overheated and often dishonest arguments about it”;  Obama said, „As commander-in-chief, I make no apologies for keeping this country safe and secure through hard diplomatic work on the mild warstorm.”  On July 23, in the White House cabinet room, Obama met with a dozen undecided Democrats in the House of Representatives to discuss the deal and seek their support.  Formal negotiations with JCPOA began with the adoption of the Joint Action Plan, an interim agreement signed between Iran and the P5-1 countries in November 2013. Iran and the P5-1 countries began negotiations over the next 20 months and agreed on a framework for the final agreement in April 2015. In July 2015, Iran and the P5-1 confirmed the agreement on the plan along with the „roadmap” agreement between Iran and the IAEA.  On October 13, 2017, President Trump announced that he would not proceed with the certification required by the Iran Nuclear Agreement Review Act, accused Iran of violating the „spirit” of the agreement and urged the U.S. Congress and its international partners to „address the many serious breaches of the agreement so that the Iranian regime can never threaten the world with nuclear weapons.”  However, on Tuesday, many opponents of the agreement argued that Obama`s non-ratification had allowed President Trump to unilaterally end it. According to Sen.
Ben Sasse (R-Neb.): „Donald Trump is not breaking the contract. … President Obama made a bad deal with Iran without the support of Congress, and today, President Trump is withdrawing from President Obama`s personal commitment, and he doesn`t need congressional support. The Rep. Ron DeSantis (R-Fla.) tweeted that „President Trump has every right to withdraw the United States from an Obama executive agreement.” Reuters reported that exemptions had been granted to Iran by January 16, 2016.
