I would not call splitting the baby progress.
Not when you put it like that! Lol
Vietnam, for instance, wasn’t liberated through division. It had to be reunited before either half was free from civil war. Same with Germany. Or Korea, for that matter.
In those instances splitting may have been an important step forward even if it wasn’t the final step. (I don’t remember the context that well for those examples) (I looked it up, at least in Vietnam, idk how you expected them to go forward without splitting given all of the external pressure.)
I think the world will always be in flux. Do you think we’ll eventually just have a static set of countries with static borders and all of the people will be happy? If so, I’d love to hear why. If not, then by what actions do you suppose those nations change to deal with ever evolving groups, environment, genes, etc? Why would secession be particularly worse than other options?
For example, I’m not so sure the legitimacy of North Korea is affirmed by the existence of south Korea more than it is affirmed by their allies (China, Russia, etc). Why would we focus on South Korea seceding more than other countries supporting?
Man this is really getting into the weeds. I don’t have those histories in my head well enough to talk about specifics like that. (Though I do appreciate all that you wrote. It is interesting to read.)
Me either.
I’m pretty sure the main focus is just about the abstract idea of a group wanting to leave a larger group.
Secession is anarchist in the sense that it rejects and fractures a dominant power in favor of one that better represents folks. So not full anarchist, but definitely more in that anarchist than restricting that ability.
Secession is a tool. Of course there are going to be bad examples, but that doesn’t mean it’s never justified and never a good way forward.
What if you had just been annexed? Not allowed to try and leave?
