Very happy to hear this TL will be continued.
Some questions on the fate of the smaller colonies:
-Did the US still buy the Virgin islands from Denmark? They bought it out of fear that Germany would be able to get them in 1917. Given the increase in German power, I would think the purchase still occurs here. The purchase also ended US claims to the northern portion of Greenland, so if it doesn't happen, this territorial dispute would still occur.
-Will France be selling off its Caribbean and Pacific colonies? There was a proposal in OTL for France to sell those colonies off, because they were not economically significant and the French government wanted to use the money to rearm before WWII. In this TL, France has even greater economic burdens after losing the Great War. Japan's adventure in Vietnam demonstrated that France can no longer project force into the Pacific, making its remaining colonies there sitting ducks. The USA, for its part, would not want Germany getting the Caribbean colonies to threaten North America, and would not want Japan to expand its reach in the Pacific. France and the USA have good reasons for a deal like this to go through.
-How are Spain and Portugal doing with their colonies? Would they be interested in selling to Germany or Britain out of fear of losing them? Portugal joined the OTL WWI against Germany but am unsure in the timeline if it happened. If it did Portugal would be dealing with a hostile Germany on the continent. Italy would love to purchase the northern Morocco to get access to the Atlantic, and I'm sure that would be the next goal of Italian Empire supporters.
