Now that Obama signed the Pacific Free Trade Agreement, as an American, I should be able to bid for Aussie bases just like the Canadians with US bases right? Since they're CX bases, it should be based on seniority only right?
You already can. There is already an American along with the rest of the united nations on the "Australian base". I think they have a token Australian in each state to give the appearance of being an "Australian base" rather than a "base in Australia".
