I'm only part of the way through reading this TL (it's probably too late to change anything about this) but I'd just say that what happens to Morocco ITTL in the Scramble for Africa seems very odd. In OTL, Morocco was the first ally of the USA, first country to recognize them, and they maintained a closeness for a long time- and I believe this was prior to the PoD, so would still be the case here- so if anything, I'd have expected TTL's America, being stronger at the time of the colonization of Africa, to try to ensure Moroccan independence and even possibly get Spain to hand Ceuta and Melilla back.Germany and France were Europe's other big colonizers, and it showed. Germany claimed the whole of central Africa in a plan they called "Mittelafrika", while the French wanted everything from the Lake Chad Basin to Morocco. Germany also had a growing presence around the Gulf of Arguin. France, deemed a bit unstable even by its closest allies, was ultimately one of the biggest losers at the Conference in comparison to its grand ideas. Morocco was given to Spain, France was shut out of West Africa save for a tiny strip in Bénin, and Germany walked away with the jackpot: all of the Congo Basin, Kamerun and Equitorial Africa, a large swath of the northwestern coast (most of which was barren desert, but still), Namibia, and the small part of East Africa not already claimed by Britain. Algeria, Tunisia, the Chad Basin, Eritia, and Madagascar were all that France managed to snatch up. Spain, whose empire had been limited to just Puerto Rico and the Philippines following the Latin American Wars of Independence, was the unforeseen victor of the conference, unexpectedly being granted Morocco, Rio del Oro, and parts of Equitorial Africa and Somaliland. Those lands, as well as New Guinea and many Pacific islands, put Spain back on the map as an up-and-coming world power, somewhere on the same power scale as their sibling Portugal.
Is there any particular reason why America allowed their oldest ally to become a Spanish colony?
