Background
Any one of these answers: World War I, World War II, the Korean War, the Vietnam War, or the Persian Gulf War. The list runs across the century and shows a changing pattern. The two world wars were declared by Congress, fought with mass conscript armies, and ended in the total defeat of the enemy; the later conflicts were never declared, were more limited in aim, and ended without that kind of resolution. American deaths give the scale: about 116,000 in the first war, over 400,000 in the second, 36,000 in Korea, 58,000 in Vietnam, and under 400 in the Gulf War. Since the 1800s and the 1900s are separate questions, keep the Civil War and the Spanish-American War out of this one.
