From JCPOA exit to the 2026 deal: How US-Iran ties soured under Trump
The United States and Iran are set to sign an initial agreement in Geneva on Friday, mediated by Pakistan, to end the US-Israel war on Iran and begin 60-day negotiations. While details are undisclosed, US President Donald Trump emphasized Iran's nuclear program as a key concern. Relations between the two countries deteriorated significantly under Trump, beginning with the US withdrawal from the 2015 Joint Comprehensive Plan of Action (JCPOA) in May 2018. Following the withdrawal, the US imposed new sanctions on Iran in August and November 2018, targeting various sectors including oil and banking. In April 2019, Trump designated Iran's Islamic Revolutionary Guard Corps (IRGC) as a foreign terrorist organization, leading to retaliatory measures from Tehran.
