I have a hard time seeing a "North Atlantic Union" - from a US perspective; but the Atlantic Rim countries do have common interests.
I also suggested an ATO as a futuristic possibility, where ATO could be Atlantic Treaty Organization (military) or Atlantic Trade Organization (economic), or both. However, in considering this futurism, I suggest re-viewing the video "Cowboys herding cats" for a perspective on what would be involved.

"Atlanticism" is supposedly Zarkozy's motive (see links in my prior post).

Since we (US) have a "more perfect union", I see no need for a "North Atlantic Union" - especially when the EU has not advanced to the point we were at under the Articles of Confederation.[*]

But, at all costs, avoid "Running with the Squirrels" - and never, never get into the cage with This Cat.

[*] As to successful confederations, I can think of only two large-scale examples: the US and Canada. The Swiss also come to mind on a smaller scale.
