Military pay, ammunition, tanks, planes, and compensation for dead and wounded soldiers, all contribute to the GDP figures. Put simply, the war against Ukraine is now the main driver of Russia’s economic growth.
And it is a war that Russia cannot afford to win. The cost of rebuilding and maintaining security in a conquered Ukraine would be too great, and an isolated Russia could at best hope to become a junior partner entirely dependent on China.
Putin is losing but also he is winning. Rússia cant defeat ukarine but also will wipe out europe. Styrofoam satelites but also Space nuclear weapons. Etc etc etc
