War in Sabah: A Sign of Disintegration of Malaysia

Sabah was not (and supposedly is not) a part of Malaysian territory. As quoted from Wikipedia, the history of integration of Sabah began in 1963 when most ethnic community leaders of Sabah, namely, Tun Mustapha representing the Muslims, Tun Fuad Stephens representing the non-Muslim natives, and Khoo Siak Chew representing the Chinese, would eventually support the formation of Federation of Malaysia.
