I was thinking what would have been the fate of the Philippines if German and later British and Malaysian Mindanao and Spanish Visayas if they were given to the US like Luzon.
Luzon or rather the Tagalog republic is now 70% Tagalog speaking including the regions 1-3 which have Ibanag, Pangasinense, Kapampangan and Ilocano as significant linguistic minorities and region 5 which have a Bicol Majority and they have a united identity as Tagalog Nationality tracing to the Katipunan, Luzon when during the American occupation either killed or expelled its Chinese and Spanish Affiliated population which was supported by the local populace which was supported by the Americans as the Americans also blocked the Hispanic and Chinese populations in their main territory, the expelled Spanish and Chinese population migrated to Spanish Visayas, while Visayas would be under the Franco dictatorship and became independent under the name Filipinas in the same time as Spanish Sahara, while Mindanao was sold to the Germans and was given to the British on WWI and later became part of Malaysia.
What if the weakened Spanish chose to war with the Americans instead of doing a settlement where in the Americans bought Spanish Pacific, Luzon and Cuba and the Americans get all of the Spanish East Indies, Cuba and Puerto Rico.
If the Americans acquired German Mindanao and Spanish Visayas would the people of Luzon or Tagalog republic treat the people of German Mindanao and Spanish Visayas as their own people or treat them as their colonies.
