The Vietnam War was a war that occurred from 1959 to 1975 in the normal timeline, and resulted in the Communist North Vietnamese takeover of Vietnam. Though the United States had been a major participant in the war, by 2015, relations between the U.S. and Vietnam had improved to the point that USAir advertisements for surfing there were seen in downtown Hill Valley.
In 1985A, however, the war was still ongoing under the lengthened administration of President Richard Nixon. Thankfully, after Marty McFly burned the Grays Sports Almanac in 1955, the timeline was restored and this never happened.
Behind the scenes
- The "Surf Vietnam" advertisement seen in 2015 may have been a reference to the 1979 movie Apocalypse Now, which took place during the Vietnam War. In one scene, Lt. Colonel Bill Kilgore ordered his men to capture a particular village near a beach so that he could go surfing there.
