U.S. Defence Secretary Pete Hegseth said on Monday, "We fight to win," and added, "as the president warned, an effort of this scope will include casualties." U.S. General Dan Caine, the chairman of the Joint Chiefs of Staff, said, "This is not a single overnight operation," and added, "We expect to take additional losses and as always, we will work to minimize U.S. losses. But as the secretary said, this is major combat operations."
