It depends on your personal situation but en general, I’d say helping to spread the revolution in your own country would be more beneficial. A revolution can not succeed in the long run to establish Socialism when it’s isolated in one country and also the momentum of a successful revolution in a neighboring country can be incredibly powerful. Just look at the revolutionary shockwave that the bolshevik revolution sent through Europe.

If it has a language I can speak, I’m in.

I would stay bc I don’t understand Swedish and I don’t speak enough German to live in Germany

I mean, the DPRK is about as close as any other country to mine. I spent some time there but have never really had plans to move there.

It’s not always easy to do either.
