If (if..) you have at least the decency to admit what the situation really is (though of course not what - or who - led to it, that would be too much for you), then you are at least not completely out of touch with reality.
When Russians will take responsibility - like decent humans do and start to ask for forgiveness to Chechens and others that they have invaded and killed(in Chechnya alone death of Chechens was up to 300 000) and genocided - the list here is quite long for hundreds of nations(that would even be a reason to spawn religion), but up till that is not happening Russian decency level ends in Bucha.
What led to it? Putin wanting to re-establish the Russian empire as he said and wrote many times about.
It's a mystery to me, Hitler wrote exactly what he wanted to do, he did it and people were surprised. Putin wrote exactly what he wanted to do, he did it and people were surprised. A mystery.
