>>2088251You cannot build a socialist society in a vacuum. You can only build it in a nation state like Stalin did, convincing inhabitants of a nation that socialism is a way forward for their advancement.
Only after establishment of socialism in more than one nation it is possible to talk about some international socialism - you have no international socialism if you do not have socialist states cooperating with each other. This is the only way forward on this planet - cooperation of socialist nations. Not a single socialist worldwide government.
Nations are culturally, ethnically, traditionally, linguistically, even mentally distinct units of humanity - socialists can only work inside nations, for the benefit of the people in their nations and after success cooperate.
National unification projects generally fail unless one nation is way more powerful and produces major economic incentives (hence USSR was a success with Russian nation at its core - but USSR was never really a multinational alliance, it was really dominated by the Russian national spirit - that's just facts).
Generally, large nations incorporating smaller nations, forming quasi-civilizations are the most efficient way of organizing human labor.
Large nations-civilizations can only cooperate, not unite - there are too many differences, from structural to cultural. Perhaps socialist nations could unite in some far historical perspective once culture would globalize much, much more than it is today but this is a far away theoretical possibility only.
A worldwide socialist government built right now as a thought experiment would represent no one, not a single society, collective, community and would immediately collapse. A cooperative of socialist countries would've been far more efficient.
Not to mention that by robbing people of their national identity you sever their collective spirit, making any socialist cooperation whithin the state more difficult.
This problem is much harder to understand for Jews outside of Israel and Americans than for Europeans for understandable reasons.
