 It was not a good relationship. I think that would be putting it mildly. There were two events that really, I think, epitomized the relationship between the U.S. and Iran during the Trump administration. The first was President Trump's decision in 2018 to abandon the JCPOA, the nuclear deal between Iran and six world powers. He pulled the U.S. out of the deal. He reimposed unilateral American sanctions on Iran.
