Lyndon B. Johnson
In foreign policy, Johnson's presidency wanted to stop the expansion of Marxist–Leninist governments. In 1964, Congress passed the Gulf of Tonkin Resolution. This made the U.S. become more involved in the Vietnam War. More American soldiers were sent to Vietnam, and as the war continued, American deaths went up along with deaths of Vietnamese civilians. In 1968, the Tet Offensive happened, which made the public start to dislike the war. Many people wanted the U.S. military to no longer be in Vietnam.
