I’ve heard this song before: “the weapons aren’t getting to the front because they’re all being sold for bribes and graft”, coupled with “the only reason Russia is losing is because NATO is providing Ukraine with all this advanced weaponry.”
The real question is why do you care so much? Why not spend energy fighting to save your own country from the guy that you are supporting in a war that is across the globe in a corrupt country that is used as a laundromat for corrupt western politicians?
