I posted one of the analysis but there are more. The Russians claimed mass murders but the real evidence is just not there.
For instance, the UN investigation found "mass graves" but most in the graves were old people that had died of natural causes and were buried there because the turmoil prevented normal funerals.
I think we have all learned that Russia has little or no credibility.
I am not an apologist of the corrupt Ukraine regime but facts are facts.
However, regardless of what happen in the past, there is no excuse for Russia to be doing what it is doing now to the civilians.
