Why Trump suddenly reversed war decision when US forces were loaded and ready to strike Iran?

Tensions escalated dramatically as reports suggest the United States was just hours away from launching military strikes on Iran before the operation was abruptly halted. According to officials cited in multiple reports, U.S. naval and air forces had entered final preparation stages, with munitions readied and strike plans approved. However, the mission was suddenly called off after a last-minute decision from President Donald Trump, who reportedly referenced a potential diplomatic breakthrough. The sudden reversal shocked military planners already in position. The incident highlights internal confusion between political announcements and operational military planning during a rapidly evolving Iran crisis.
