Explain the impact the Vietnam War had on America politically and socially.

The United States had entered the conflict in Vietnam as the world’s superpower following its decisive victory over the Axis powers in World War II, but left Vietnam with a humiliating defeat, shockingly high casualties, American public sharply divided and its leaders uncertain of what lay ahead in foreign policy. The nation’s longest and most debilitating war - the only war the U. S. ever lost, had far-reaching consequences and impact on most aspects of American life from the economy, culture to domestic politics and foreign policy - some of which continue to do so today.
