Donald Trump is intensifying his efforts to address Iran’s nuclear ambitions. After withdrawing from the 2015 nuclear deal (JCPOA), he reimposed sanctions, citing Iran's support for militias like Hamas and Hezbollah. Iran has subsequently ignored some of the deal's restrictions and enriched more and more uranium nuclear fuel: analysts fear it could soon be capable of making a nuclear warhead. Trump has reinstated his ‘maximum pressure’ strategy, imposing additional sanctions, but he has now agreed to direct discussions between US and Iranian officials in Oman. However, the USA is demanding full dismantlement of Iran's nuclear programme, a request Tehran will find difficult to accept. Iran’s hardliners view nuclear deterrence as essential, and past negotiations show how challenging these discussions can be. Israel insists on the complete dismantling of Iran’s nuclear capacity, while military action remains a possibility if talks fail.
