While the deal itself contains no provisions for withdrawal, Iran has threatened to reactivate its nuclear program if the United States reneges on any of its obligations under the pact’s terms. Iran has long alleged that the United States has violated the deal by continuing to make it difficult for U.S. and international companies to invest there, despite the removal of sanctions. In return, nuclear-related international economic sanctions were lifted, and the United States agreed to activate waiver provisions for its unilateral sanctions. Trump, who criticized the Iran deal throughout his presidential campaign, said in January that the United States would “withdraw” unless the agreement was rewritten to address his concerns. Some foreign policy experts said that canceling the Iran deal could send a message to Kim’s regime that the United States is an unreliable negotiating partner.
