The US and Iran are still far apart ahead of nuclear talks. The US president has sought peace in Gaza and Ukraine, bombed Yemen, and launched a global trade war. Now he is turning his attention to Iran, which has always been on his agenda. The issue remains the same: what can stop Iran from seeking a nuclear weapon? Iran denies having such ambition, but other countries believe they want at least the capacity to build a nuclear warhead. The US pulled out of the 2015 deal with Iran, and Iran has since ignored some of the deal's restrictions and enriched more uranium. The US is now hoping to match economic pressure with diplomacy and has offered to begin negotiations with Iran.
