Iran deal: Expert describes 'dilemma' Trump adminstration faces US President Donald Trump grudgingly agreed not to reimpose nuclear sanctions on Iran, but officials warned that it would be the last time he issues such a waiver. Trump also imposed sanctions on 14 Iranian figures and companies. Conflict resolution specialist Robert Malley, who helped broker the Iran nuclear deal under the Obama administration, cautions that while some sanctions "are completely consistent with the deal", Trump's motivations may not be and could lead to Iran deciding "it's not worth it for them".
