US divorcing EU?

My critique of the EU for a long while has focussed around the risk of it becoming a barrier to greater integration around the world rather than helping it, despite the fact that the Euromaniacs want it to lead to greater integration within its borders. For me the building blocks of global interactions should be nation states, not continent-wide bargaining blocks which could hold back consensus. Against this background this story from EU Serf is fascinating. Some in the US are waking up to the barrier the EU could present. Let us hope this is not a portent of things to come.
