Poland will bring you into war with the allies, only way to avoid war is to back down over Danzig.
This kinda hurts, I believe u give up those 3 cores in Poland and your sliders get moved the wrong way. The Soviets may not attack Poland and you'll be worse off than if you partitioned it. You also start further back giving the Russians that many more rivers to defend and also you may have to fight Polish and Russians at same time. Also theres a good chance you'll end up at war with the allies anyway and Vichy wont fire if your at war with the Soviet Union. A complete conquest of France is very hard , you have to take out central Africa as well. I don't think Bitter peace can even fire if your still at war with France.
