U.S. President Donald Trump issued a blunt ultimatum to Tehran, warning that failure to sign a nuclear agreement will result in devastating consequences. While confirming a ceasefire remains intact following recent naval skirmishes where U.S. forces destroyed attacking Iranian boats and drones, his overall message was heavily uncompromising. Trump noted that ongoing negotiations are actually progressing well, but firmly reiterated his vow to permanently block Iran from ever obtaining nuclear weapons. In a stark threat regarding the potential collapse of diplomatic talks, the president warned that any end to the current ceasefire would result in “one big glow” rising from Iran. Despite the harsh rhetoric, Trump confidently suggested that Tehran’s weakened military leaves them eager to finalize a pact before facing further conflict.
