To dispel your mischaracterization of my views, though, I'll answer your gross mischaracterization.
Imposed amalgamations that won't defend themselves deserve whatever they get when they won't defend themselves. They don't deserve a defense by other nations not threatened by a particular outcome. If the EU or Poland want to send men to defend the Ukraine, they should start soon. Time is a wastin'.
If the countries you hypothesize "should be taken over by Germany because they had weak leaders" are amalgamations that won't defend themselves, so be it. If they are in fact sovereign nations full of people who identify themselves as citizens of said sovereign nation they'll defend themselves and they have the right to determine their own internal affairs without others coming to their "aid" when the real problem is internal with a propaganda icing of "external threat" on it.
Now answer the questions. Start with my question about what's to keep the Ukraine from Ukraine collapsing into butchering one another along ethnic or other lines as soon as an outside force provides them the cover to do so. There's nothing in their history that leads anyone to believe they're not more than happy to slaughter one another and yet, your comments make the point that they should be segregated along ethnic lines as soon as possible and that people who intermarry with "ethnic Russians" are a threat to the State.
So, SOP would seem to be ethnic segregating leading to, what? Is that equal treatment under the law? What law, the eugenics laws that pass out citizenship rights based on who you marry and who your parents were? Where have we heard that one before and how did Ukrainians side with the nation that promoted that worldview?
Obvious evasions, changes of subject, and ignoring the questions, all lead to a single conclusion about the nature of a given poster as do comments such posters make that clearly show reality is not first and foremost among their concerns.
have a nice day now, ya' hear
I'm not sure what the bit about segregation comes from. In a wartime situation, potential enemy aliens - especially those in senior government positions - need to be vetted for their loyalty to the state. During WWII, this meant the internment of Japanese citizens along with small numbers of German and Italian nationals. It occurred all over the world, not just in the US, and remains standard practice in most countries. That is why you will not find Arabs in make-or-break government positions in Israel, just as you won't find Muslims in equivalent positions in India.
For a more recent example, it is empirical fact that Slovenes, Croats and Bosnians defected to their ethnic groups' respective Territorial Defense units within days of the Wars of Partition. For Ukraine's government to not consider the possibility of treachery from within would be foolhardy in the extreme.
