After reading up a bit on the Spanish East Indies, as well as early Filipino nationalism, I've wondered... What if somehow, for instance via avoiding the Spanish-American War, Spain retains control over the Philippines? Or, more accurately, portions of the Philippines. Iloilo in Western Visayas for instance was very loyal to Spain and most of the revolutionary activity was limited to Luzon after all, so could Spanish control have continued in Visayas and, say, the Zamboanga Peninsula, as well as Basilan Island?
