Owen caused a bit of a kerfuffle here yesterday by drawing a parallel between Greece leaving the Eurojail and the Amurrican South seceding during the recent unpleasantness. Some readers seemed to think that if he approved of the one he must approve of the other.
It is a mistake to think that the same question always has the same answer. Keeping the US together -- on Northern terms -- was a great idea in 1860. But it's a terrible idea now, and the world would be a better place if the US were somehow to split into nine or ten reasonable-sized countries, with fantastic crinkled borders. My favorite one is the idea of a River Principality extending about a hundred miles either side of the Mississippi and stretching from Chicago to Nawlins. Texas, of course, would be given back to Mexico, with a sigh of relief.
Same holds for the EU, of course -- except that the EU was never a good idea. In fact I'd go farther and split up Germany. Make it like 1648 all over again. Oh and that chimaera 'Greater Britain' -- independence for Wales, Scotland and Cornwall at the very least, and reviving the Heptarchy wouldn't be a bad idea either.
