The US president, speaking at the inaugural meeting of his Board of Peace in Washington DC, insisted Iran could not have a nuclear weapon and emphasised that “bad things will happen” if the country continued “to threaten regional stability”. The White House envoys Steve Witkoff and Jared Kushner met Iranian officials in Geneva to discuss Iran’s nuclear enrichment programme, set back but not eliminated after US and Israeli bombing during the 12-day war last June. After the diplomatic meeting, Iran promised to respond within two weeks to US demands that it abandon enrichment altogether in return for sanctions relief – roughly consistent with Trump’s mooted timeline. However, last summer Trump gave himself two weeks to decide whether he would bomb Iran’s underground nuclear enrichment facility at Fordow, only to strike it with B-2 stealth bombers within a few days. Iran deal prospects will be clear within 10 days, Trump says as military buildup growsA second carrier strike group, led by the USS Gerald R Ford, is en route to the region.
