With America's sons in the fields far away, with America's future under challenge right here at home, with our hopes and the world's hopes for peace in
the balance every day, I do not believe that I should devote an hour or a day of my time to any personal partisan causes or to any duties other than the
awesome duties of this office the Presidency of your country. Accordingly, I shall not seek, and I will not accept, the nomination of my party for another term
as your President.

- President Lyndon B. Johnson, March 31, 1968

Which action taken by the U.S. Government increased American involvement in the Vietnam War?

1. Marshall Plan

2. Gulf of Tonkin Resolution

3. Yalta Conference

4. Nazi-Soviet Pact

Answer 1

The action taken by the U.S. Government that increased American involvement in the Vietnam War was the Gulf of Tonkin Resolution. The Gulf of Tonkin Resolution was a joint resolution of the U.S. Congress that authorized President Lyndon B. Johnson to use military force in Southeast Asia in response to alleged attacks on U.S. naval vessels in the Gulf of Tonkin by North Vietnamese forces. The resolution was passed on August 7, 1964, and it effectively gave the President a blank check to escalate U.S. involvement in the Vietnam War.
