It was a synthetic government and we even know how the participants were selected and who selected them:
That's a coup.
Ukrainian parliament voted. The president ran away.
Nothing synthetic here. Just special pleading from Russia.
And you still have no explanation as to why 27% of "Ukrainians" decided not to identify as Ukrainian citizens, according to your own sources. Probably an undercount, given that the baseline was in 2016.
I don't need an explanation. I showed that more than 50% of the Ukrainians want to remain Ukrainian, that's in the actual Donbas areas. That's no reason to break international law, attack a sovereign country, threaten the world with nukes, kill innocent people, destroy a country, and so on, when you're a big d1ck nuclear power, and second best army in the world, with UNSC P5 status, OSCE status, Council of Europe member, etc. Over what?
Nothing here justifies a full own Hitler like war of aggression.
You can try to find imperfections in Ukraine but no country is perfect, but sure as fsck, Ukraine did not invade anyone and is only defending their borders and national integrity in line with the UN Charter. Russia must fek out of Ukraine and shame on you for supporting Hitler 2.
