This Guardian article by George Monboit asserts that there is only one way to check American power and that is to support the euro. I find this amusing on two counts. First that, as the article asserts, "we have a moral duty to contest the developing power of the United States" and secondly that the way to do it is through the Euro. There are some ideas in the article that, at first blush, might appear to be reasonable, but in fact I doubt they'll actually have much affect on the power of the US. US power comes from many more places that just the Dollar (although that is a piece). Our cultural hegemony is not linked to the dollar, for example.
