In 1967 President Lyndon B. Johnson gave this speech addressing the situation in Vietnam and the United States' military commitment there. This speech was part of a broader effort by Johnson's administration to justify and intensify American involvement in the Vietnam War.

The speech included the announcement of an increase in U.S. troop levels by an additional 50,000 soldiers. This decision brought the total number of U.S. military personnel in Vietnam to approximately 525,000. Johnson framed this escalation as necessary to counter the aggression from the North Vietnamese and the Viet Cong, reflecting his administration's commitment to the containment of communism, a cornerstone of U.S. foreign policy during the Cold War.

The speech was part of Johnson's policy of gradual escalation, aiming to increase military pressure on North Vietnam to bring about a favorable negotiation of peace.
The reaction among the American public to Johnson's announcement and the ongoing war effort was mixed and increasingly polarized. Initially, a substantial portion of the American populace supported Johnson's policies under the broad anticommunist sentiment of the Cold War era.

However, as the war dragged on, public opinion shifted significantly. By 1967, the growing number of casualties, the draft's impact on American families, and the visible lack of progress in achieving military and political goals in Vietnam led to mounting opposition. This shift was reflected in widespread protests, particularly among younger Americans and the academic community, who became vocal critics of the war.

In Congress, Johnson's decision to escalate the war initially received substantial support, especially given the broad bipartisan consensus on containing communism. However, as the war's costs in terms of lives, economic impact, and its divisive effect on the American public became clearer, skepticism in Congress grew. This skepticism was not immediate and took several more years to fully develop into the widespread congressional opposition that characterized the latter stages of the Vietnam War. The turning point in Congressional support generally came after the Tet Offensive in 1968, which significantly altered perceptions of the war's winnability and legitimacy.

Thus, the 1967 announcement by President Johnson marked a critical point in the Vietnam War, leading to increased military commitment on the part of the United States but also sowing seeds of widespread discontent and opposition that would profoundly affect domestic politics and the overall direction of U.S. foreign policy.
