President Donald Trump is preparing to deliver an Iran policy speech Thursday, in which he is expected to say that the landmark 2015 nuclear deal with Tehran is no longer in the US national security interest.

Mr. Trump faces an October 15 deadline to notify Congress whether Iran is still complying with the nuclear accord and that the deal serves American interests.

Secretary of State Rex Tillerson said Wednesday that President Trump’s national security team has prepared a recommendation on how to proceed that contains several options, recognizing that the nuclear deal is just one element of overall Iran strategy.

The US president has called the 2015 agreement between Iran and six world powers one of America’s “worst and most one-sided transactions” ever.

Analysts say the future of the nuclear deal may hinge on a face-saving fix for Mr. Trump so he doesn’t have to recertify the Islamic republic’s compliance every ninety days.

US officials say the mandated reviews have become such a source of embarrassment for the president that his national security aides are seeking ways for him to stop signing off on the seven-nation accord without scuttling it entirely.
