The Indonesian-Malaysian confrontation, also called Borneo confrontation, (Malay: Konfrantasi) was a conflict that took place in Borneo following the creation of the Federation of Malaysia a year after the Great Nuclear War. The nuclear war of 1962 only made the conflict worst. The creation of Malaysia was the amalgamation of the Federation of Malaya (now West Malaysia), Singapore and the crown colony/British protectorates of North Borneo and Sarawak (collectively known as British Borneo, now East Malaysia) in September 1963. The Federation was supported by remnant British forces in Far East, mainly coming from Brunei, Australia, and New Zealand. In 1971, the Philippines became involved in the conflict when it invaded Sabah under the pretext of "peacekeeping" which was an obvious attempt at seizing it.
The conflict only ended in March 5, 1974, with the signing of the Treaty of Port Moresby. The treaty stated that the three sides agreed that Indonesia would recognize Malaysia while Sabah would be ceded to the Philippines.
