"The new European Union is redefining the role of the nation state without replacing it."
This quote illustrates just how little the author understands of what he is supposed to be an expert in, i.e the nature of the state and the societies it rules over.
There is no such thing as a "nation state", but only mercenary "patron states" deceitfully posing as nations, in order to legitimise themselves, their ruling elites and the immense power they wield and abuse, to their own personal advantage and that of favoured (especially wealthy) clients, at the expense (and ultimate self-destruction) of society at large. This is why all past civilisations have fallen, as will ours if it continues along its current path.
Why does the author not recognise this?
Because, as a privileged client (and employee?) of the state himself, he too has a massive personal self-interest (subconscious more than conscious) in rationalising and defending its role, self-image (as our "nation") and ideologies (social, political, economic and racial, formerly religious), on which it bases its claim to moral and knowledgeable authority.
Anyone wishing to understand the true nature of the state must view it from a human-evolutionary perspective (LINK to introduction to such a perspective).
