Western Ukraine is part of Ukraine only since after WWII. That's the problem. You can not impose the will of minority to the majority and still have democracy. People who do not speak Ukrainian language are forced to use it.
IMHO, Western Ukraine taken from Poland should be returned to Poland and much of the trouble would be resolved. The rest of Ukraine (Orhodox Christians) would find a way to cooperate and arrange workable state.
Breaking up Ukraine along the lines of Czechoslovakia is the best solution.
The West can join the EU and NATO and the East can join Russia’s Customs Union, the CIS and the CTO.
Who is being hurt by a scenario? No one.
Apart from the fact that you’ve misidentified the minority, you have a point.

Thank you for the Russian (Putin) point of view

If we wanted to take Western Ukraine, we wouldn’t need your stinking “permission”.
