The First Republic wouldve been a success if the Americans had recognized it. Bonifacio, popular? I dont think so, Aguinaldo was supported by mainly from the bottom of society to the very top of society during his presidency, by all classes. there is no multinationalism in the First Republic and the elites and higher ups of society wanted a united Philippines meanwhile the rest of society as long as theyre fine about it as long as they can live their lives like normal. The Visayas republic joined the republic, the Negros Zamboanga and other republics wouldve joined the Philippines if the Americans didnt go and invade the place.Bonifacio was popular amongst the commoners that supported the revolution as he was from a more humble background. Aguinaldo was a pampered rich boy who more likely than not bribed Bonifcaio's allies into betraying him. And the First Philippine Republic was doomed to collapse anyway due to factionalism and multinationalism, it pretty much choked on its own vomit as the Americans walked in.
There was already a united front to Filipino nationhood during the revolution
More like what would happen is other countries just do a dollar diplomacy battle plays different sides and be the biggest winner of Asia.
