You can' really blame Putin for not trying to prevent an armed conflict (Minsk 1, Minsk 2, Instanbul talks) for many, many years. Internally, he is often heavily criticized for being 'too soft' when dealing with the Collective West. In fact, it was the US, EU and NATO that finally pushed the Zelensky regime into open warfare.
Let's be honest, there are war crimes committed on both sides on a daily bases (killing of ethnic Russians by Ukrainian troops in eastern Ukraine that are waiting for the Russian army, killing of POWs), I regularly watch them on Ukrainian and Russian Telegram channels. But your claim that Russia 'commit all these war crimes' is just not a serious argument. If you think it is, please provide a list of 'all these war crimes'.
