The United States is moving B-2 bombers to the Pacific island of Guam, two US officials told Reuters on Saturday, as President Donald Trump weighs whether the United States should take part in Israel's strikes against Iran.It was unclear whether the bomber deployment is tied to Middle East tensions.The B-2 can be equipped to carry America's 30,000-pound GBU-57 Massive Ordnance Penetrator, designed to destroy targets deep underground. That is the weapon that experts say could be used to strike Iran's nuclear program, including Fordow.The officials, speaking on the condition of anonymity, declined to disclose any further details. One official said no forward orders had been given yet to move the bombers beyond Guam. They did not say how many B-2 bombers are being moved.The Pentagon did not immediately respond to a request for comment.
