In light of the continuing unraveling of the United Nation's relevance and creditibility, I think it is increasingly important to talk about the alternatives. James C. Bennett's Anglosphere is one of those. I suppose that another would be something called "a coalition of the willing," something that, while it isn't a permanent, formal relation whose existence would stretch beyond the conflicts that sire them, is currently in operation in two places in the world.
I like Bennett's idea, however, because it is not a collective built around race of Anglos, as it is one built upon English ideas of governance, law, and freedom. So, it can (and does) include people other than Anglos. Here's Bennett's book, now available, and he has website too. Also, his essay on it is still available here.
