I was commenting not on the book, but on your comment. You said "we may be one nation that can be disputed" & used a book about North America support your claim.We may be one nation, although even that can be disputed, as it has been in Colin Woodard's 2011 book "American Nations: A History of the Eleven Rival Regional Cultures of North America".
Woodard doesn't claim that North America is a nation. Read the title of his work again.
That's why I reminded you that North America isn't a nation.
Says you.There is as yet no evidence to support that claim.
