A sudden surge in U.S. military air traffic toward the Gulf is raising fresh fears of a new Iran war. Flight tracking data shows multiple C-17 and C-5 cargo planes moving troops and heavy equipment closer to the region, supported by aerial refueling tankers and surveillance aircraft. The buildup comes as Iran pushes a ceasefire plan while warning Washington to lift its blockade. Donald Trump has signaled doubts about reaching a deal, even as military options remain on the table. With both sides hardening positions, the risk of escalation is rising fast.
