DBWI: a United Philippines

The American Senate did not rattify the treaty of Paris and instead supported the Magdiwang Party and later the revived Tagalog republic which rule Luzon now, this country is known for copying Haiti by kiling the remaining Spanish colonizers and their sympathizers and stamping out Spanish and the remaining colonizers and sympathizers went to Visayas and Mindanao..

The Spanish retained Visayas and Mindanao until 1940’s which became a country and the Sultanates of Mindanao and Sulu are still independent by now..

What if the Americans acquired and united the Philippines? Any ideas?
