there's no reason to doubt him.. Ukraine hasn't tried any mindless, meat grinder offensives, and the front line hasn't moved against Ukraine significantly since about the 6 month mark.. there's no reason to believe they've lost many more than that, while it's easy to believe the Russians have lost 10 times that number or more.. most of the Ukrainian casualties have been innocent civilians.. babies, women, children, etc.. the Russians have not shown themselves capable of defeating Ukrainian military units..
