During the time between the passage of the Gulf of Tonkin Resolution and the start of the Tet offensive, what happened in the Vietnam War? South Vietnam surrendered to North Vietnam. Peace talks between South Vietnam and North Vietnam were conducted in Paris. All U.S. civilians were evacuated from Vietnam. The U.S. government deployed more troops to Vietnam.

The correct answer is: The U.S. government deployed more troops to Vietnam.<br /><br />During the time between the passage of the Gulf of Tonkin Resolution in 1964 and the start of the Tet Offensive in 1968, the U.S. government significantly escalated its military involvement in the Vietnam War. This period saw a substantial increase in the number of U.S. troops deployed to Vietnam, as the U.S. aimed to prevent the spread of communism and support the South Vietnamese government.<br /><br />The Gulf of Tonkin Resolution, passed by the U.S. Congress in 1964, authorized President Lyndon B. Johnson to take military action in Vietnam without a formal declaration of war. This resolution followed reported incidents in the Gulf of Tonkin involving U.S. naval vessels and North Vietnamese forces.<br /><br />As the war progressed, the U.S. government's strategy shifted towards a more aggressive military approach, leading to the deployment of more troops and an intensification of combat operations. The Tet Offensive, launched by North Vietnamese and Viet Cong forces in 1968, marked a significant turning point in the war, as it exposed the vulnerabilities of the U.S. and South Vietnamese forces and contributed to growing anti-war sentiment in the United States.
