Lucas actually has directly stated that the original Star Wars trilogy was to some extent based off of the Vietnamese resistance to Western Imperialism.

“We’re fighting the largest empire in the world, and we’re just a bunch of hay seeds in coonskin hats that don’t know nothing,” he says, referencing the American Revolution against the British Empire, and how he based the heroes of Star Wars on real-life rebellions against powerful empires.

Lucas and Cameron discuss how during the Vietnam War, America became “the Empire.”

“The irony is that, in both of those, the little guys won. The highly technical empire – the English Empire, the American Empire – lost. That was the whole point,” Lucas says.

Another part of this same discussion with James Cameron, from another article:

Cameron pointed out how the Rebels are a small group using asymmetric warfare against a highly organized Empire. Today, Cameron added, the Rebels would be called terrorists. “When I did it,” Lucas replied, “they were Viet Cong.” In other words, Lucas viewed the Vietnamese as the rebels and America as the invading villains.

He further explained that Star Wars was a “vessel” in which to place his worldview that the United States had become an empire during the Vietnam War, doomed to fail like every empire before it.

Its uh, honestly rather obvious, but uh, right wingers consistently fail at basic media literacy, so … ?
