Even if you have proof of that, which you don't, that's already years after 2014 when Russia actually started this war and the mass killings.
And you calling Putin's invasion a "special military operation" is a clear sign you are nothing but a reality-denying propaganda machine.
I support people in subterritories like Donetsk and Lugansk voting for independence if they want to, but Putin does not sponsor free and fair votes or referenda.
