We Can Change the World Forcefully

Davis accurately depicts the United States government's conception that we are supposed to save the world from "evil" forces like communism. I believe he shows how America became intoxicated with their newly acquired power over the world after World War II and ultimately shows America's wrongfully justified wrath on a mostly peasant country.
There was a since of duty in Americans then to better the world, to rid it of evil forces like the Nazis. American citizens thought their government couldn't be wrong after WWII and the American government took advantage of this to pursue personal agendas. They went into Vietnam to prevent the spread of Communism in a newly free country. They did it forcefully. And they were wrong.
American soldiers and American citizens began to see it. Journalists like Susan Sontag wrote about how wrong our government was for attacking the Vietnamese. Davis filmed it. After all, the Vietnamese were fighting the French for independence just how the Americans did against the British two centuries before. This is why America was wrong.
Ho Chi Minh talked of admiration towards the United States and their independence and protection of individual liberties. Why could the Vietnamese not have the same? Their own form of it should be allowed. Why did America have to intervene? They were hypocrites. It was a contradiction of their own values.
