Yup. Often when “It is a period of civil war” the rebels are horrible people, as we saw in the US civil war. Also Star Wars takes a lot from WWII, a conflict where an Alliance (Allies) defeated an Empire. Actually multiple Empires.

The uniforms of the Star Wars Empire look a lot like the German Empire, and the trench run was like a dam-busting bombing run and Hoth was like Dunkirk. But the allies had significantly more resources than the Empires had in WWII. Also the Allies was the side that built a super weapon.

So… what should we learn from Star Wars? I dunno… fascism is bad even if they might have cool uniforms. That and… pew pew pew voom voom.
