Fresh fears of a renewed U.S.-Iran war erupted after reports claimed Donald Trump could authorize new strikes on Tehran within the next 24 to 48 hours. Analysts told Al Jazeera that Trump faces mounting pressure from hawkish advisers and Israeli Prime Minister Benjamin Netanyahu after ceasefire talks stalled again. The warnings surfaced amid tensions over the UAE nuclear scare, failed negotiations and Trump’s difficult China trip with Xi Jinping. Critics now say the Iran conflict has become politically costly for Trump, while Washington appears increasingly unable to walk away without claiming a decisive victory against Tehran.
