I would encourage you to pull this book from the library. The lines dividing Europe’s ethnicities and nations (not the same thing) have been rearranged a couple times a century on average. It is simply not America’s problems. The Ukrainians have been involved in vicious ethnic cleansing between themselves and the Poles and the Russians through history. It is just NOT our problem.
But this is a great book and I can't recommend it highly enough.
There is no justification for Russia's military invasion of Ukraine.
There was no trouble there, even Putin had to admit that.
This is nothing but a geopolitical land grab because Putin could
get away with it - counting on the weak "simply not our problem"
wishful thinking that prevails with our leaders today.
Hitler had the exact same ideas as Putin with his land grabs -
and we saw how rolling-over led to the holocaust.
Ukraine doesn't exist in a box...
look at the example you are making for China, North Korea, Iran, etc.
I have a book for you:
