I haven’t seen The Force Awakens yet. I’ll get there soon. In the meantime, I decided to rewatch the first six. I will defend III as a respectable movie other than some terrible writing for Anakin and Padme. I won’t defend I and II at all except for one area of the plot that does always interest me: the rise of the Empire.
Prior to the events that open the first movie, the Galactic Republic had been in relative peace for a long time. Of course there’s still violence on the individual level up to the planetary level, but there’s no large-scale warfare like that which characterizes the six movies.
The Republic didn’t even have an army. They had the Jedi, who are probably best compared to the best-case scenario of police. They do not use force unless absolutely necessary. They don’t enforce laws which aren’t hurting anybody, but they do step in – including with some calculated violence if necessary – to help alleviate conflicts. I’m definitely not pretending they were pacifists, but they would probably mostly align with the goals of Just War theory. That was it for state violence, probably about as close to a utopia as possible.
