Vietnam War
After the alleged second attack, the US launched air strikes against North Vietnam. The Congress passed the Gulf of Tonkin Joint Resolution (H.J. RES 1145) on 7 August 1964 and so gave the president the power to run large-scale military operations in Southeast Asia without declaring war. There was little to no proof of the attacks, and it was believed by some that they had been an excuse for expanded US involvement in Indochina.
