what Allowed the president to take any action that he believed was necessary to maintain international peace and secure Southeast Asia without Congressional approval.

The Gulf of Tonkin Resolution, which was passed by Congress in 1964, allowed the president to take any action necessary to maintain international peace and security in Southeast Asia without the need for specific Congressional approval. This resolution granted President Lyndon B. Johnson broad powers to use military force in Vietnam in response to alleged attacks on American naval vessels in the Gulf of Tonkin. This resolution effectively authorized the escalation of the Vietnam War without requiring a formal declaration of war from Congress.
