They lost so much equipment in the initial offensive. They clearly assumed it would be a cakewalk and that they could mirror the US invasion of Iraq, but the level of corruption at play and the lack of maintenance of armour in long term storage (tyres, cannibalization of parts and rations for sale on the black market etc) appears to have left them with significantly reduced capacity. Obviously that’s a good thing, but it’s also led to far more deaths than anybody expected. War is brutal, but this shit is extraordinary.
Obviously they have nukes, but they can’t use them without an overwhelming international response. What’s confusing is that they have plenty of high altitude bombers that would be difficult to shoot down. Carpet bombing the Ukrainian front line would yield better results for the Russians but they just don’t seem to be willing to go there, and as a result an order of magnitude more people will die for Putins hubris. It’s disgusting. The only winners in this conflict will be the western military industrial complex, banks, and construction companies, and while those things are necessary evils, it isn’t something that should receive unquestioned overwhelming support from the people. War is evil, period.
