USA fought a long, bloody war in this country and withdraw in 1975.

Answer 1

The country you are referring to is Vietnam. The United States fought in the Vietnam War, which lasted from the late 1950s until the fall of Saigon in April 1975. The war was characterized by significant military engagement, heavy casualties, and widespread protests in the U.S. and around the world. The U.S. eventually withdrew its combat troops in 1973, but the conflict continued until the North Vietnamese forces captured Saigon, leading to the reunification of Vietnam under Communist control.
