^ Ridwan, you are msising the fact that if Indonesia DID pull a full scale assault on West Papua in this TL the Aussies would flip, hit back, and almost immediately unless both sides backed off the US and PRC would be in it in no time. The only reason the invasion worked in OTL was because President Ford wanted Sukarno on his side and Australia was in the midst of a constitutional and political crisis at the time. (Not to mention that bastard Bjelke-Petersen and his racism not liking the Papuans.)
Indonesia would have to get the Aussies out of the way before West Papua is in play. More than likely, Papua New Guinea - all of it - would become Australia's seventh state, with full representation in Canberra, because if Indonesia is a key player in a rival bloc no way is the US going to allow Indonesia to even threaten Australia, and if Australia wants to keep New Guinea, they'll be able to. The end of the White Australia policy in 1973 and simply changing political attitudes in Australia would allow New Guinea to integrate into Australia fairly easily. Especially once Bjelke-Petersen goes down in flames, like he inevitably will.
