At least four American servicemembers have died in the ongoing U.S. offensive against Iran. Donald Trump released a video on Sunday, announcing the deaths of three service members. General Dan Caine, chairman of the Joint Chiefs of Staff, said the military expects to take more casualties as operations continue. Hegseth used the term "war" to explain the operation. The offensive against Iranian is unpopular and threatens a destabilizing quagmire in the Middle East.
