To use the example already given, how about Ukraine? I have a very hard time not placing that in a good vs evil framing.
It’s true that Ukraine isn’t perfectly good, and Russia isn’t purely evil, but it’s pretty damn close.
Here’s a nation that was just keeping to themselves and growing closer to the ones that didn’t want to annex them (surprise surprise) and the evil overlord thought that was too threatening and decided to pre-emptively annex them.
