In the 1960s, the students were the first group to protest US involvement in the Vietnam War.

Indeed, the students constitutted a major force to bring change during the 1960s. According to students, war was not necessary because isntead of being triggered by the aim of justice, it is driven by a desire for power and greed. In spite of the fact that the opinion and fight of students were significant in the decision-making process at that time, the war continued until the 1970s.

That would be the students.
