You are painfully ill informed.
Or maybe you are 90 plus years old and suffering from cognitive decline?
The fact that eastern Ukraine was until recently part of Russia and is populated by Russians who have voted repeatedly and with huge majorities that they want to rejoin Russia means nothing?
Muh Russia muh Russia muh Russia - let’s start WWIII because we are ignorant fools with zero historical context.
The fact that eastern Ukraine was until recently part of Russia and is populated by Russians who have voted repeatedly and with huge majorities that they want to rejoin Russia means nothing? Not true. Ukrainians are the majority in eastern Ukraine and every poll showed that the majority of residents wanted to be part of Ukraine. Russians were a majority only in Crimea.
According to a 2001 census, ethnic Ukrainians make up 56.9% of the total population of Donbas as a whole with ethnic Russians making up the largest minority, making up 38.2% of the total population of Donbas
