This document begins with an exposé of the twenty-period between 1942 and 1962, covering the Pacific War in West Papua (1942–1944) and the nation’s twelve years as a UN Non-Self-Governing Territory (1950–1962). The third section details the legal manoeuvring by Indonesia, the United States, and the United Nations to turn the Non-Self-Governing Territory into an Indonesian colony. The fourth section sketches the West Papuans’ program in 2020 to be registered on the UN Decolonisation List. The final section is a Q&A rebuttal of the claims used by Indonesia to takeover and occupy the 459,412 kms2 of richly resourced Melanesian land. 'West Papua 1942 to 2019: the legals, the politics, and the only way forward' was first presented at the Pacific Institute, Australian National University on 28 November 2019.
