DUBAI — Iran's state media has mocked U.S. President Donald Trump after new details emerged about his secret aircraft switch during a visit to Turkey, saying it showed just how nervous he is about the Islamic Republic's power. "Again, Trump, with his new scandal, has become the top subject in the U.S. media these days. A scandal stemming from fear of Iran’s military power, a power that caused Trump, last month, while returning from Turkey, to secretly switch his plane," said a presenter on state television, adding that the episode has become a source of "humiliation" for Trump. A threat that Air Force One could be targeted by a shoulder-fired missile prompted the Secret Service to secretly move Trump onto a smaller government jet, a person briefed on the matter said. The threat emerged on the final day of Trump's visit to Ankara for the NATO summit, the source said, as tensions run high due to the ongoing U.S. war on Iran. The Secret Service deemed the threat to be credible and imminent, prompting an extraordinary operation to conceal the U.S. president's movements. The New York Ti
