Answer: Eventually, participation in the Vietnam War leads to major oppression and mass anti-war protests.
Explanation: The Vietnam War was highly controversial and divisive, leading to widespread opposition both within the United States and around the world. As the war escalated and its human and economic costs became more apparent, many people became increasingly disillusioned with the conflict. This dissatisfaction with the war's objectives and conduct fueled mass anti-war protests, with millions of people taking to the streets to express their opposition. These protests were not only a rejection of the war itself but also a broader critique of government policies and the military-industrial complex. The anti-war movement played a significant role in shaping public opinion and ultimately contributed to the eventual withdrawal of U.S. troops from Vietnam.
