It is often stated the causalities are a low number. The truth is no one knows what they really are other than they are many times that what is reported. Many dead are in buildings that are unsafe to enter or there just is not the resources to count. This is a movie about Kharkov where Russian troops do not have the ability to capture the city, so they just shell it mainly with rockets. This is the type of place where war crimes will be considered. If you watch the video, you will see it is not because the Ukraine military was hiding in the buildings because the front line was nowhere near these places. This shows the city and how it has been damaged because of the now mostly failed Russian invasion.
There are recording of Russian troops being told to fire on civilian area and when the gunner asked to repeat the order it is repeated. When the gunner says these are civilian areas the person giving the orders says he knows. Look at the footage of Kharkov and get an idea what this looks like. This is the stuff war crimes is going to be based.
What would be Russia style is that there is a pause in the war coming soon. Then in about a year there will be another war where they try to fix the problems they are having with this war and once again to rid the country of NAZIs.
