Let’s take a look at Russia’s cake. Most Russians spend 80% of their income on food. Russians bury dead soldiers in mass graves. There is no payment for war dead without a body and proof the death was in battle. By the way the promise of wages is also a game by Russia. It is called I win you lose. Or we will pay ya later.
Food production is down which is why food price inflation is high, more like 30% but not potato, the there is a potato crop failure. Business are going bankrupt. Yes lots of spending on military cost. After the war their will be many burned out tanks and mines to dig up.
The blown up oil refineries and loss of customers needs to be accounted for. How have you counted that into GDP?
