The biggest issue is the justification, or lack thereof, for Russia claiming Ukraine as its own and attempting to conquer the country. Others include Russian demands that NATO troops be removed from Poland in the baltics, Russian threats towards Finland and Sweden, and how the Western response to the Russian invasion may affect China's willingness to invade Taiwan.
The battlefield propaganda regarding the exact number of Russian troops killed, the Ghost of Kiev, etc, have nothing to do with any of that.
