They really are just sending their "junk" into battle, explains why they're not arsed about losses
Maybe it's not incompetence but wants to let the West think it is incompetence, perhaps Putin was speaking truth when he said he was prepared for everything the West would do to him & Russia and he wants to be disconnected from the global economy for more smoke & mirrors and he somehow has a plan to destroy the global economy when our guard is down and we're least expecting it when Russia look their weakest, he will strike and his master plan starts making sense.
To be honest I'd rather this than the idea he has lost his mind and is in charge of all those nuclear weapons and if it did happen, he deserves to rule the world for such genius
