I'm gonna nitpick on a point people in the West routinely miss or get wrong: Thus Russia, which was then named the USSR, regained its historical lands The entity that now goes by "Russia" was then known as the Russian Soviet Federal Socialist Republic or RSFSR. It's important because people often repeat that Ukraine "separated from" Russia in 1991. No. That's the year both former Republics got their independence from the USSR. Ukraine was not a part of the Russian state as it's constituted now. RF is not Russian Empire nor USSR any more than Turkey is the Roman Empire. Ukraine is a "new" country in the exact same sense as Russia is; both nations are technically 33 years old. P. S. for the same reason, they're neither "defeated Nazis" nor "paid the highest price" for defeating the Nazis. In fact, territories that suffered the most in WWII and the first part of XX century are now Ukraine.
