I Think The UK Just Did Something Very Smart
The UK did something very smart when they refused to join the Euro. While the decision was widely derided at the time, in retrospect it was brilliant. Keeping their own currency let them set monetary policy rather than having it imposed on them.
I think they just did it again. By refusing to join the Euro rescue plan that would have cost them much control of their own country I think they remain their own country after the rest of Europe has been reduced to vassals of Germany. And things are never run for the benefit of the vassals.
Cameron, I salute you!
