Answer:
Nixon withdrew troops mainly because of pressure from American protestors
.
Explanation:
Since its beginnings, the Vietnam War was an unpopular phenomenon in the American society. The image of the United States engaging in an external conflict, facing an impoverished society and generating large numbers of deaths of civilians and combatants, added to the televising of many situations of the conflict, caused many American citizens to demonstrate against the war.
In addition, the hippie counterculture, which was at its peak in the 1960s, and the pacifism of university students that emerged in response to the Cold War, gave the rest of society a platform to initiate protests, marches, and demonstrations against the conflict.
As the war unfolded and American citizens learned of the great massacres in Vietnam, in addition to the enormous numbers of young Americans who were being sent into the conflict (many of whom did not return alive), society as a whole He began to call more emphatically for a way out of the conflict. Finally, after the Tet Offensive in 1968 and the enormous amount of casualties that it caused to the American forces, the recently assumed Richard Nixon began the process of Vietnamization and gradual withdrawal of troops in 1969.
