The U.S. and Iranian negotiations have stalled, with only days left before a ceasefire ends. Despite President Donald Trump expressing optimism, Iran's chief negotiator, Mohammad B. Ghalibaf, however, noted a significant gap in understanding between the two countries. The talks are focused on fully reopening the Strait of Hormuz and limiting Iran's access to nuclear weapons. The U.N. military has continued its blockade of Iranian ports, a violation of the ceasefire.
