Ukraine isn’t targeting ethnic Russians.
Furthermore, what do you mean by “ethnic Russians”? Someone who speaks Russian as his native language? There are plenty of Ukrainians who do, including Zelensky.
What about those whose parents came from what is now Russia? Lots of Ukrainians have one or both parents from Russia, but feel Ukrainian.
Zelensky didn’t “shut down opposition parties”. He shut down 3 parties that were a fourth column for Putin and he shut them down now, during Putin’s invasion. The leading opposition parties are still around.
Don’t be surprised when you guys start getting the Orban treatment, due to your internal policies, and it will likely be worse, once you’re no longer of use to the EU and Media.
