They’re all headed for rule by the European Union.
Break apart, reassemble the way you want. Rinse, repeat.
I read that if Scotland breaks away, they will not be automatically a member of EU -- tho I'm betting the busybodies in Belgium will try to recruit them; but membership isn't transferrable. They have to re-form a government and make it official.
btw, I sincerely hope UK votes UKIP and ditches the EU.
