The 2015 Iran nuclear agreement has effectively curbed the Persian Gulf nations nuclear ambitions, according to U.S. Director of National Intelligence Dan Coats.
We continue to assess that Iran is not currently undertaking the key nuclear weapons-development activities we judge necessary to produce a nuclear device, Coats told the Senate Intelligence Committee on Tuesday. "Irans continued implementation of the JCPOA [Joint Comprehensive Plan of Actions] has extended the amount of time Iran would need to produce enough fissile material for a nuclear weapon from a few months to about one year.
Coats, who was appointed by Trump in 2017, also pointed out that Iran had threatened to resume nuclear activities if it does not see the trade and investment benefits of the international agreement. Trumps withdrawal from the treaty last year, coupled with his administrations decision to reimplement harsh sanctions targeting the country, have threatened the likelihood of those economic benefits from materializing.
CIA Director Gina Haspel, who also spoke at the intelligence committee hearing, agreed with Coats's assessment, saying Tehran "at the moment, technically they're in compliance" with JCPOA.

So basically, it's Trump, Pence, and any other idiots, versus people who actually know what they're talking about.
