In OTL, notions of a divided Berlin first arose in the London Protocol of 1944, where the Allies formally agreed on 4 occupation zones for France, Britain, the US and the Soviets. Once the Soviets occupied Berlin in May 1945, it took until July 1945 to transfer control to the other Allies of their respective occupation zones in Berlin. In this timeline, there was no London Protocol, because Russia is just the enemy of the enemy, whereas in OTL the US and Britain sent a lot of supplies to the Soviets. NATO is in full control of Berlin and until some kind of peace deal has happened to determine the future of Germany, the situation remains as it is.And there goes Germany again, and in no less than 6 occupation zones! No 6 zones in Berlin though ?
