The east of the island became independent (from Australia) in 1975 and is now Papua New Guinea. Meanwhile, the western half was handed over to Indonesian control following the end of Dutch rule, a status formalized through the controversial, UN-backed 1969 "Act of Free Choice" in which a tiny, handpicked group of local leaders voted under military duress to integrate with Indonesia.

Is it not rather down to identity? If the victims had paler skin and a different religion, we'd never stop hearing about it. But unfortunately for Papuans their complexion is too dark for international media to care and the perperators are with "You-Know-Who".
