The deal is supposed to restrict Iran's nuclear operations in exchange for relieving the Islamic Republic of crippling economic sanctions, namely those the United States and the United Nations have imposed.
The American President is already in talks with his French counterpart Emmanuel Macron on a new agreement with Iran.
Trump gave Britain, France and Germany a May 12 deadline to fix what he views as the deal's flaws - its failure to address Iran's ballistic missile program, the terms by which inspectors visit suspect Iranian sites, and "sunset" clauses under which some of its terms expire - or he will reimpose US sanctions. In a moment of candor, then-Secretary of State John Kerry admitted "we are not fixated on Iran specifically accounting for what they did at one point in time or another" - but then he promised Congress that Iran would provide the accounting.
Texas Sen. Ted Cruz slammed the signature Obama foreign policy achievement as "not just unfixable, but truly catastrophic", as he detailed the damning evidence against Iran and the disastrous deal in a series of tweets last week.
The 2015 nuclear deal between Iran and world powers saw Tehran limit its enrichment of uranium and number of spinning centrifuges, as well as hand over its stockpile of uranium and reconfigure a heavy-water reactor so it couldn't produce plutonium.

United States prosecutors charge former VW chief Winterkorn
The U.S. government believes Winterkorn is in Germany , so it's unlikely he'll ever see a U.S. courtroom or jail. Winterkorn became the ninth person to face U.S. criminal charges in connection with the scandal.
Kerry's involvement in trying to preserve the deal after leaving office came as a surprise to foreign policy experts.
But the obscure 18th century law has never been used to prosecute anyone - although it was raised to criticize Mike Flynn for his discussions with the Russian ambassador after the 2016 election. According to a source, this is the second time Kerry has met with Zarif in the past two months. Speaking to the BBC, Mr Guterres said there was a real risk of war if the 2015 agreement was not preserved.
Meanwhile, Israeli President Benjamin Netanyahu has been pushing Trump to take a more aggressive posture toward Iran, Israel's archenemy. In fact, such a rupture could have even more drastic consequences, such as a decision by Iran to renounce the agreement or even to withdraw from the Nuclear Non-Proliferation Treaty. If the agency cares for its own credibility as a nuclear watchdog, it should decide that Iran's past declaration was false and that Iran's retention of the documents obtained by Israel, with all the nuclear know-how they contain, put it in likely breach of the agreement.
The five-minute video shows Zarif behind his desk, delivering his message on the deal. And it now appears that the response from some Europeans has been to offer the United States more concessions; from our pocket.
In a sensational presentation on Monday evening, Netanyahu showcased an enormous trove of Iranian documents that he said proved the existence of Irans nuclear Project, Amad, which Tehran claimed to have frozen in 2003.
