Just to keep the focus on the border irrelavance thing, what do you think are the denominators driving the relationship between US/Canada & EU? What are the must have's and the must have nots in the environment to make that kind of union work?
let me give europe as an example since countries there have fought more bloody wars than India and Pakistan have....but after destroying each other twice within the space of 40 years they realized that it was not working for either of them....so they buried their differences and look at france and germany now
