My Ancestors were slaughteringthe frencha nd Germans for Centuriesma nd Vice Versa, now they sort of play nice and have a common currency and have eliminated many restrictions to travel, work, etc.
I have a red Passport, British, but I can walk into any Euro Country and live and work there, and one Currency is the norm for almost 20 countries.
Canadians and Americans are Transplants, chances are we alll came from the same village over there, but Ed is right, it will not happen.
The Europeans speak a differant language, have differant customs, and can agree, but Americans and Canadians who kinda speak the same language, both like Shanai Twain, have generally got along, will never agree.
My toothpaste, deoderant, shaving cream, underwear, all came from the US, but there will never be the same co-operation that Europe has achieved.
