I have a great idea.
Why don't the Russians living in Ukraine migrate to Russia? Then the fighting would stop and the Ukrainians can stay in Ukraine.
Besides, this war makes it harder for Putin to loot more billions from Russia.
What do you think of my idea, comrades?
Because the difference between Russians and Ukrainians is very loose and it becomes non-existent in the east. It's like, somewhat the difference between the French in France and those in Geneva canton
In fact, in the east, they won't call themselves "Russians" but they'll speak Russian only and won't know "Ukrainian" -- which itself is a language continuum rather than a truly defined language (I know, I know you can argue it is a defined, but this is really recent and hasn't "set" in the same way as say Russian or Romanian etc)
"why don't the Russian-speaking Ukrainians migrate to Russia?" well they will say that they are really part of this land. you must understand that most Ukrainians don't have this idea of a nation, more of a sense of "we are from here" -- they've not had the chance to develop the deeper sense of culture
