Which event is associated with Richard Nixon's presidency and escalated protests in the United States?

The Vietnam War is closely associated with Richard Nixon's presidency and significantly escalated protests across the United States. During Nixon's time in office, the conflict intensified, particularly due to the administration's policies, which included the expansion of the war into neighboring countries like Cambodia. This led to widespread public outcry, protests on college campuses, and a growing anti-war movement. The sentiments surrounding the war were fueled by rising casualty figures, graphic media coverage, and a perception that the government was not being transparent about the war's progress and objectives. As a result, the Vietnam War became a focal point for civil disobedience and activism during Nixon's presidency, mobilizing citizens across the nation in opposition to the conflict.
