This movie realistically shows how generation after generation of servicemen sacrifice themselves for their brothers in arms and for the love of their country, despite popular opinion.
Not much respect is given to the Vietnam Vets. Unlike the WW1, WW2 and Korea vets who got parades when they came home after defeating the totalitarian, national socialist, and communist regimes, the Vietnam vets were harassed and disrespected by the media. War has never changed, just our perspective of it.
People ask, what was the point of Vietnam. The point was this: America doesn’t stand for bullies. Never has, never will. I personally know people who without intervention in Vietnam would not have had the opportunity to escape to the US and live a better life.
