Fresh signs of a possible military buildup are emerging in the Middle East as dozens of U.S. aerial refueling aircraft are reportedly stationed at Israel’s Ben Gurion Airport near Tel Aviv. Images appearing to show KC-46 and KC-135 refueling tankers have intensified speculation that Washington could be preparing for a wider confrontation with Iran if ongoing negotiations collapse. U.S. President Donald Trump said tensions with Tehran are “right on the borderline,” warning that the situation could escalate rapidly if talks fail. Reports also suggest the aircraft may remain in Israel through at least the end of 2027, turning Ben Gurion Airport into a key military logistics hub.
