Ok for those that are bit advance in the game, i suggest that you follow the axis path and join the Germans. The reason I did that is to have only one threat in my way and that is the soviet threat and also to have the security of the German machine.
If all goes well and the Axis dominate Europe, then is going to be really easy to just finish all the rocket technologies, even if not though most of the allies are away from you and the Germans, possibly the Italians too, will work as a shield for Poland until you are done with the rocket techs.
Good luck!
