I find that you used the term (real world) political themes, as often, fictional politics are a reflection of the politics of the author , the society the author lives in, or historical political ideas.
The Star Wars political conflict (specifically the original trilogy) is about as fictional as you can get (Empire vs. Rebels). But Order vs. Freedom (keeping these ideas broad in order to stay clear of forum regulations) have political parallels throughout history.
I personally think that all works are, at least in part, political in nature. Though I know that some disagree with that assessment.
