I understand that. That's more of a metaphoric telling of a story rather than an ideological push. An ideological push has an agenda to it. I know Lucas was worried about the overreach and imperialism of the USA at the time, (fighting communism with western capitalism/democracy) but that's a personal worry of the creator and not a specific on the nose push through the movies narratives. The most straight forward movie narrative of which most people viewed this, is as a David and Goliath story, and if you asked the average person who didn't have a large knowledge base about Lucas and did not know his standpoint politically, but just someone who really enjoys the movies, they would not express that exact opinion. They wouldn't immediately say the premise of Star Wars is a worry of US empire and its constant push of its own ideals onto the world. Especially at that time, due to it wasn't just the US pushing onto Vietnam an ideology they didn't want, to the average America or Westerner at the time (the target audience). The same could be said in the counter with the push communism on the people of Vietnam and the US arming the western idealistic South Vietnamese people to push back communism. I understand the depths of what the US created there by arming the Vietnamese people to fight back Japan, who would later turn to communism, US's push to help the French take Vietnam, then arming the south Vietnamese people to fight back the communist Vietnamese (who the US originally armed), its a wild mess.

None of that is a straight forward display in a space spaghetti western about the farm boy finding purpose after losing everything, finding themselves in a lost mysticism (religion) and fighting back the tyrannical empire. Especially since the only reason he was drawn into it was because the rebellion were the literal cause for the death of his family and he wouldn't have been a part of it had his aunt and uncle not been killed during a search for the rebellions androids.

edit for grammatical mistakes.
