The Gulf of Tonkin incident was an international confrontation that led to the United States getting more involved in the Vietnam War. The event included (potentially) two confrontations between North Vietnam and the United States in the waters of the Gulf of Tonkin.
The result of the Gulf of Tonkin incident was the passage by Congress of the Gulf of Tonkin Resolution. This allowed the President to assist Southeast Asian countries that were threatened by communist aggression. In this way, Johnson was able to justify the deployment of more troops in Vietnam.
