What outcome do you expect from capitalist development? These countries all magically reform into socialism?
They will develop along the same lines as capitalism always develops, and when the capitalist crises finally hits they will turn to fascism and a block will form to steer a fascist dog into attacking the communist opponent in the world stage. The level of unity that exists within this block will, in my opinion, be larger than it was last time because they will have learned from the mistakes they made, they have learned by now that nazi germany should have been their ally and not their enemy.
