Why this is the answer
The 1900s means the years 1900 to 1999, the 20th century. During that time the United States fought in World War I, World War II, the Korean War, the Vietnam War, and the Persian Gulf War (1991). Any one of these is a correct answer. Be careful not to name a war from another century, such as the Civil War (1800s) or the wars after September 11, 2001.
