Not just former USSR. Ukraine has been part of Russia for 200 years. For the 400 years before that, mostly Poland. Except for 3 years around 1919, they have not been a country since the 12th century. That’s reality.
The “reality” is that is not your decision to make. About 40 million Ukrainians would disagree with you. Right now they are busy ejecting an invading horde from their “not a country.”
