Reason No. 6: Portugal

...reflects the fact that Nazi Germany had no intention to conquer the African colonies of then fascist governed Portugal (23). A revision of this policy was inteded only if Spain was not to join the axis (38).

We can assume that Portoguese dictator António de Oliveira Salazar in this time alternative would have behaved in the same way like in real life. In real life he stayed neutral but also offered Britain and the United States naval and air bases on the Azores and Madeira (46). Given that the course of war was fortunate for the axis, leading to Spain joining in, Portugal would have made this offer to Nazi Germany. With this cooperation secured, Germany would have had no reason to attack Portugal or its colonies.
