The Final Solution involved exterminating the Jewish population. This is not the kind of Final Solution that was imposed by Russia on millions of Ukrainians via the Holodomor. Like it or not, internment in wartime is a standard treatment for potential enemy aliens. While the long term solution to Russian irredentism may be expulsion, just as Germans were expelled from Danzig, Konigsberg and the Sudetenland, it's not clear that Ukraine is anywhere near that point. Only time will tell.
Why should the EU, the US, or anyone else lift a finger to help people who are infatuated with the idea of an ethnically pure State not unlike the State Nazi Germany envisioned for Germany?
Now about my original questions . . .
