I was told that the Indonesians have some interest in Luzon due to it being a part of Majapahit as Saludong according to a person who i talked on another forums and also due to Negarakertagama, I am thinking what if the Indonesians decided to war with the Philippines to annex both Luzon, Miangas and Sulu from the Philippines in the 60's-70's what would be the consequences of such war..
