What was a main reason the us decided to end involvement in the vietnam war? a) the vietnamese government decided to adopt a diplomatic government instead of a communist government b) increasing anti-war protests across the us fueling the anti-war movement c) the us was also fighting in western europe and could no longer fight on two fronts d) all of these

The correct answer is B.

During the late 1960's and early 1970's, there were several protests all over the country regarding the US military actions in Vietnam and other countries in this region. Two of the most famous ones were the Kent State and Jackson State protests. In both these events, college students protested against US involvement in Vietnam and the possible invasion of countries near Vietnam. This resulted in a standoff between college students and national guardsmen at Kent State. In the end 4 students were shot and killed by the Ohio National Guards. In the Jackson State protests, 2 people were killed.

The killing of these protestors sparked more outrage in America and only continued to fuel the anti-war movement.
