But the more important question then becomes: why shall the Russians living in Ukraine since generations suddenly be 2nd class citizens in Ukraine?
I'm sure Russians living since generations in Ukraine won't mind, they speak perfectly well Ukrainian of course. Or don't they, because they would consider it a second class language in Ukraine? Yes, indeed, that's exactly their problem.
But Russians are free to speak Russian. And Russian is still the official language of Russia. Ukraine isn't forcing Russia to change their official language to Ukrainian from now on.
See, isn't that nice of Ukraine?
The conflict is about national security of Russia: Ukraine poses a real threat to Russia
That's actually true. But not because of NATO, but because Russia considers Ukraine to be their colony. And they can't allow a colony to become independent of Russia. That would make a very bad example for other Russian colonies and the whole dominance of Russia.
And it did. An epic fail for Putin to say the least. Nobody fears Russia anymore. Russian dominance is done.
Ukraine immediately would start a war against Russia to "re-take Crimea"
We'll see what will happen to Crimea.
Russia is the only grown-up people in this kindergarden to see this upcoming threat and prevented this danger of WW3.
Good to know that there won't be a WW3 because Russia will prevent it. I know there won't be a WW3. But I wouldn't mind anyway. I'm grateful for the many brave men and women who fought and gave their lives in WW2 to destroy fascism. As a German, I know very well whom to thank for the privilege to be born and raised in a free world and not in a fascist Nazi country. And I will always be thankful for that and never forget it. If time comes for me to give my life now for the freedom of the next generations, I wouldn't hesitate at all - and be proud of it.
These Western politicans are "
dumb like bread", as a silly German saying goes

, for example the German FM Annalena Baerbock is such one

Dumb like bread! Really!
Coming from you, I take it as a compliment for sure. Indeed, Annalena is doing a great job. Thank you.
