Japan, Australia, and the Pacific Rim in the early 1980s:
For the East Asian and Pacific Rim countries, the fall of Indonesia to Communism was to mark a steady growth of a new, unlikely set of alliances. For the countries of Indochina and Malaya the fear that Communist Indonesia might begin influencing domestic issues began to lead them to seek a general alliance with both Australia and Japan. For Japan this came concurrent with a slow push for a more-modernized Japanese Navy, in the wake of political upheaval in both China and Russia. For Australia this marked, together with New Zealand, some of the first steps to a full, regional hegemony.
The Australian occupation of part of southern New Guinea was further strengthened by the Communist takeover in Indonesia, and one of the first instances of aggressive Communist actions was to happen when the Indonesian regime began to prop up the Red Front, a mixture of tribal forces and nationalists in New Guinea that proceeded to fight a desultory guerrilla war with the Australians.
This pattern further consolidated a push for a military alliance of Pacific Rim states, an alliance formed in the pivotal Treaty of Tokyo, where the Japanese, Vietnam, Laos, Cambodia, Malaya, Singapore, Australia, New Guinea, and in a significant instance of Korean autonomy not in this case challenged by Imperial Russia due to the enemy targeted formed a Pacific Alliance of Free States. To form the alliance was one thing, to make the alliance into a functional, viable military bloc would be something else again and took the duration of the 1980s to establish a Joint Command, and to work out such basic issues as a common language of command, how leadership would be structured, avoiding potential neo-colonial friction between Japan and Indochina, and the necessity on the part of Australia and Japan in particular to build up more formidable, more technologically advanced military machines.
In the later 1980s the Philippines would join this bloc when an Indonesian-backed group of Communist revolutionaries on Mindanano and Samar led them to see this alliance as serving their own interests, thus further expanding one of the first independent military blocs in the world. Ironically the military and economic recovery of China in the 1990s and particularly in the 21st Century would lead to a more, not less, militarized view of the purpose of the PAFSJC.
