Good morning fellow Field Marshalls, I come up to you with a problem in my Ironman game.

As Italy, I successfully defended the Mediterranean theatre, sunk the Royal Navy battle fleet and pushed back the British into Egypt, before taking out the British Isles. In the meantime, my Charlie Chaplin-moustached friend with the help of my armoured corps has pushed the Soviets back almost to the Ural mountains and brought them to just 28% of their victory points.

Now it's 1944 and the Red Army is using sheer numbers (penal regiments) to push the front west and since we are more or less out of supply range I can't counterattack effectively with anything. Possible solutions?

TL,DR: Fascist Italy wet dreams in WW2 are now "real" but Stalin is throwing thousands of men to the west, help
