Not really. The Unites States has its share of warcrimes and don't care much about collateral damage but they don't make it a policy to beat, rape and shoot every civilian they can get their hand on, and they don't seem to establish torture basements in every single village they take over.By your description, Russia appears to be fighting Ukraine in the manner that the United States and its hapless allies regularly fight their targets.
I don't doubt the US military has little regard for civilians in conflict areas, but going out of their way to do genocide doesn't seem a consistent habit of the US army.
After the Russian army...ahem I mean ''separatists'' already took over those areas.... after those areas were attacked by their governments.
