The issue fast approaching is that the Allies are compeltly spent as a fighting force but fight on because they will collapse in on themsevles if they stop. Nothing short od insurrection will stop them.
The Cominterns? They're running out od men, pure and simple. They could do with a decade or more of peace before the final push, which they will definitely win. That's the frustration. They are so close to total victory but won't achieve it. They'll break before the allies do. Ironically, a similar situation to Russia's war with japan in the early 20th century.
