Looking at the world and various causes and desires for independence etc...one can think that China, one day will devolve from one nation back into 3, then into 30, then into 300 etc. Hong Kong could be a separate independent state, just like Timor L'este. Yes, that could happen. Hawaii could kick out all Americans and be Independent, yes, that could happen. The Dharug tribe, from Cronulla to Palm Beach and inland to the Blue Mountains, could kick out everyone else in Sydney, Tibet could kick out every Chinese person who isnt ethnically Tibetan from Tibet province, that could happen, the Manchurians could kick out the Han in Northern China and launch a horrid war on Japan, Australia could kick out the American Military from Darwin and from Pine Gap, except, well, in reality, where we actually live, none of those things are ever going to happen. Not ever. As for Ireland, Jesus, the only thing actually stopping the Irish from being one Ireland/One Island, are the Irish.
