IMO Rusky industry is in munitions and delivery systems manufacturing mode. If it could do so in WW2 with alot less resources, then IMO it can do so now.
That said, NATO has the capacity at present to pump alot more war materials into the Ukraine but I guess the US does not want to use its latest war tech on this war in case the Chinese would gain up to date info on US conventional war hardware & software After all the greatest threat to US global hegemony is China aided by Russia ...not the other way around
