U.S. President Donald Trump says he remains Iran's "number one target" after returning from the NATO Summit in Ankara, where Middle East security dominated discussions. During the flight, reporters were asked to lower window shades aboard Air Force One, fueling speculation over heightened security measures. Trump also switched from the Qatari-gifted Boeing 747-8 to the older Air Force One during the journey, although he denied the move was linked to security concerns. Reports from ABC News, Bloomberg, and the Associated Press say the aircraft change came amid escalating tensions with Iran.
