russia's openly stated plan to create 10's of millions of refugees by attacking civilian infrastructure (a war crime) failed
Nothing to do with Russia's plan. More will come because...
1. Ukraine is like Turkey - in ruins. Did you ever live with the windows missing?
2. Whatever Zholes will restore - over time and at great expense - Russia can and will destroy in seconds.
3. Standard of living is higher in Poland than in Ukraine hence no reason to go back. Would you?
4. The more of them, the more they will feel at home and will feel less need to do back to Ukraine for sentimental reasons since they bring Ukraine with them.
5. The more of them, the lower the desire to learn Polish. There are cities in the US where you don't need to speak English anymore.
6. Polish government will treat them as a protected minority and make Poles second-class citizens. It is already done when medical resources are allocated.
So the question is: how many Ukrainians are too many? Is there a limit? If so, why would there be a limit if they are such an asset?
