But, large parts of Ukraine were parts of other countries before the Soviets took over. Parts of Ukraine were part of Russia, Poland and Hungary.
And, ethnic Russians are no obligation to live under an illegally-formed Ukrainian nationalists government that wants persecute and kill them.
You're completely ignorant and really don't care about the history of Ukraine or the people in it.
Fortunately for your ethnic Russians Putin removed most of them to Russia.
That’s rich because he did the ethnic cleansing he accused Ukraine of doing.
