LOL! So basically you are saying that ethnics in UK, France, Germany, etc etc etc should go back to their own country that they and their forefathers came from??
How bizarre!
"It's Ukraine land and no-one can change that" (your quote)?
Do you actually live in an "alternate reality".
Let me enlighten you on what the reality is right now. Part of Ukraine land (Crimea) is already a part of Russia. Are you telling us you/Zelensky will change that?
Let me enlighten you further. A large part of East Ukraine is right now controlled by ethnic Russians supported by Russians and will likely become a part of Russia just as Crimea is a part of Russia. Are you/Zelensky going to somehow change this reality?
Clearly you have little idea of what you are talking about!!!!
