military- US pulls out of vietnam
On January 27, 1973, the parties agreed to a cease-fire the following day, the withdrawal of all U.S. forces, the release of all prisoners of war, and the creation of an international force to keep the peace. The South Vietnamese were to have the right to determine their own future, but North Vietnamese troops stationed in the south could remain. By the end of 1973, almost all U.S. military personnel had left South Vietnam.
