But in Star Wars 7, the Resistance, against what? The Empire lost and there is a peaceful republic, so how did the new villains acquire the Republic's ships? Why did the Republic give them away? But above all, what the hell is the Resistance resisting for 34 years if the Empire lost in the early '80s?
Or do I need to rewatch Return of the Jedi? I really don't understand how this 7 works.
