A break-up of the eurozone and possibly the EU (see below) as well might create a new opportunity to establish a treaty grouping called the Anglosphere, which would include the U.K,, the U.S., Canada, Australia, New Zealand, and possibly Ireland, if they were interested. I imagine it as a free-trade zone initially, and possibly more integration later.
All of these nations share a legal system basis (I think), a language, and significant cultural heritage. I can see substantial advantages to this treaty group.
Note: "Anglosphere" is not a term of my creation. A Google search comes up with "about 315,000" hits for Anglosphere.
