German controlled a few african colonies that were lost after WWI.
Assuming Germany wins WWI they are going to get a few more. This lead me to think about how Germany would act about them. In a simplistic way, colonies either are opressed to the point that they turn into a black hole in the budget or they are invested it and the people begin to rebel asking for independence. This leads me to ask what would be the "natural conclusion" of German colonialism since Germany was not a player in the post WWII colonization.
A rule is that in this scenario there is no direct danger to Germany in Europe, and as the 1960s roll in the scenarios mentioned above happen with their colonies being a black hole and/or rebelling, so they can try to hold them by force, try to integrate them into the german political structure or pull out. Since Namibia was germanized to the point that german is widely spoken today I left a option for they trying to keep only Namibia.
