The Gulf of Tonkin Resolution authorized "President Lyndon Johnson" to “take all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression” by the communist government of North Vietnam. It was passed on August 7, 1964, by the United States Congress after an alleged attack on two U.S. naval destroyers stationed off the coast of Vietnam. The Gulf of Tonkin Resolution effectively launched America’s full-scale involvement in the Vietnam War. The results are pretty simple I suppose; the United States lost the Vietnam War and Vietnam was united under a communist government.
