Gulf of Tonkin Resolution

The Gulf of Tonkin Resolution or the Southeast Asia Resolution, Pub. L. 88–408, 78 Stat. 384, enacted August 10, 1964, was a joint resolution that the United States Congress passed on August 7, 1964, in response to the Gulf of Tonkin incident. It is of historic significance because it gave U.S. president Lyndon B. Johnson authorization, without a formal declaration of war by Congress, to use conventional military force in Southeast Asia.
