We're trying to get it back because they [Taliban rulers] need things from us," Trump said at a news conference with British Prime Minister Keir Starmer. It was the largest US base in Afghanistan and served as the central command during its 20-year occupation of the country. Taliban officials rejected Trumps suggestion that the United States might regain control of Bagram, but they left open the possibility of talks to improve ties.
