Sure. Hostile alien invasion.
You read the Three Body Problem, i see
wait maybe we can scapegoat elon musk if he decides to settle on mars permanently.
In the EU we are already working on just that.
And we also have plenty of nationalist parties on the rise trying to avoid that.
Nations are defined by contrast to the outer world. So I don’t think what you are dreaming of is possible. It will always be Us vs Them.
This might seem a little naive but I’d say you need the right space to bring different cultures together, and a lot of good will! For instance, I’m thinking of projects like the Erasmus programme for students in Europe, or even constructed languages like Esperanto that aim to build bridges between peoples. If we approach things with the right angle, there’s always a way to build something with our differences, as resources and not obstacles.
Create a resource based economy that factors societal and environmental goods and losses and reward your citizens for the actions they take. It’s a gross oversimplification, to be sure, but one issue with capitalism is currency, in that it is amoral. It does not care what you do with it, and your only motive is the acquisition of it.
No. Next question.
maybe in really small counties where the population is less than a few hundred thousand
Yes, extreme violence+ethnic cleansing efforts can lead to the emergence of stable national identities. This process could be applied on a global scale to give you the results you are looking for.
Uhh…that’s the uh, nuclear option…
I think someone tried it once. It wasn’t too popular of a plan, in fact it caused a world war
To be fair, the genocide did not cause a world war. The invasion of surrounding countries did.
The world was uncomfortable chill with genocide before that.
A politic and governing system founded on the removal of others is gonna either fail because it runs out of others to remove, or, more likely, will keep making others of its own people in order to justify its existence
No one is pure. There is no such thing as a pure ethnicity. We’re not even all human, with some of us having neanderthal DNA, so creating a society designed to accept only one kind of person is effectively impossible, as there will always be hairs to split–And split those hairs they will when you found a society on the premise of blaming an other for your problems
Besides, even ethnic purity is no guarantee for stability. Countercultures exist, and revolutions happen for things besides racial means. There is still class warfare, not to mention the every-splintering world of spiritual beliefs
Ethnostates are doomed to fail
