The Vietnam was truly not a war. To justify sending troops congress called it a police action. See, calling it a war would help them to justify spending all that money so they tried to hide it from the public. When Kennedy enter Vietnam, just like the Bay Of Pigs, the plan was to scare them by force and numbers and then pull out. Unfortunately when Johnson took over he did not have the same leadership skills and did not know how to get us out of Vietnam. So Johnson sent in more troops and the war just escalated We cannot blame any one person regarding Vietnam.
