Get a history book and the read it. You'll find enough is never really enough. There's always something more, or something at all, to learn. Unless you are determined not to.
Ukraine is a country in the same way the independent states of the Donbas are. If you find the former to be enough to deter inquisitiveness the you must, by logical extension, subscribe to the latter by default. Though I get a nasty suspicion you don't.
Me, I prefer reality. Ukraine is a country for as long as the same global actors say it is, or isn't. If Putin says Ukraine is not a country and his troops make it so then your opinion bounces off the facts.
Sticking with reality, Ukraine is actually a pile of rubble, because Raytheon and Boeing wanted more money and so did Exxon and Shell. Putin said no, because his corporations said snap a fraction of a second sooner. If you think it works differently to that then bless.
