What was the Tonkin Resolution?
On August 5, 1964, President Lyndon B. Johnson put the Gulf of Tonkin Resolution before Congress. On August 7, Congress approved what soon became the legal foundation for Lyndon B. Johnson’s escalation of the Vietnam War.
It came in August 1964 with a brief encounter in the Gulf of Tonkin, the waters off the coast of North Vietnam where the U.S. Navy posted warships loaded with electronic eavesdropping equipment enabling them to monitor North Vietnamese military operations and provide intelligence to CIA-trained South Vietnamese commandos. One of these ships, the U.S.S. Maddox was reportedly fired on by gunboats from North Vietnam.
The reported attack came in the midst of LBJ’s 1964 campaign against hawkish Republican Barry Goldwater. President Johnson felt the incident called for a tough response and had the Navy send the Maddox and a second destroyer, the Turner Joy, back into the Gulf of Tonkin. A radar man on the Turner Joy saw some blips, and that boat opened fire. On the Maddox, there were also reports of incoming torpedoes, and the Maddox began to fire. There was never any confirmation that either ship had actually been attacked. Later, the radar blips would be attributed to weather conditions and jittery nerves among the crew.
According to Stanley Karnow’s Vietnam: A History,
“Even Johnson privately expressed doubts only a few days after the second attack supposedly took place, confiding to an aide, ‘Hell, those dumb stupid sailors were just shooting at flying fish.’”
Johnson ordered an air strike against North Vietnam and then called for passage of the Gulf of Tonkin Resolution. This legislation gave the president the authority to “take all necessary measures” to repel attacks against U.S. forces and to “prevent further aggression.” The resolution not only gave Johnson the powers he needed to increase American commitment to Vietnam, but allowed him to blunt Goldwater’s accusations that Johnson was “timid before Communism.”
The Gulf of Tonkin Resolution passed the House unanimously after only forty minutes of debate. In the Senate, there were only two voices in opposition. What Congress did not know was that the resolution had been drafted several months before the Tonkin incident took place. In June 1964, on LBJ’s orders, according to journalist-historian Tim Weiner,
“Bill Bundy, the assistant secretary of state for the Far East, brother of the national security adviser, and a veteran CIA analyst, had drawn up a war resolution to be sent to Congress when the moment was ripe.” (Legacy of Ashes: The History of the CIA, p. 280)
Congress, which has sole constitutional authority to declare war, had handed that power over to Johnson, who was not a bit reluctant to use it.
Testifying before the Senate, [Defense Secretary] McNamara lied, denying any American involvement in the Tonkin Gulf attacks: “Our Navy played absolutely no part in, was not associated with, was not aware of any South Vietnamese actions, if there were any.”
Three days after the announcement of the “incident,” the administration persuaded Congress to pass the Tonkin Gulf Resolution to approve and support “the determination of the president, as commander in chief, to take all necessary measures to repel any armed attack against the forces of the United States and to prevent further aggression” — an expansion of the presidential power to wage war that is still used regularly. Johnson won the 1964 election in a landslide.

One of the senators who voted against the Tonkin Resolution, Oregon’s Wayne Morse, later said,
“I believe that history will record that we have made a great mistake in subverting and circumventing the Constitution.”
After the vote, Walt Rostow, an adviser to Lyndon Johnson, remarked,
“We don’t know what happened, but it had the desired result.”
In January 1971, Congress repealed the Gulf of Tonkin resolution as popular opinion grew against a continued U.S. military involvement in Vietnam
Since Vietnam, United States military actions have taken place as part of United Nations’ actions, in the context of joint congressional resolutions, or within the confines of the War Powers Resolution (also known as the War Powers Act) that was passed in 1973, over the objections (and veto) of President Richard Nixon.”
The War Powers Resolution came as a direct reaction to the Gulf of Tonkin Resolution, as Congress sought to avoid another military conflict where it had little input.

In 2005, the National Security Agency (NSA) issued a report reviewing the Tonkin incident in which it said “no attack had happened.” (Weiner, p. 280)
