A country is made up of people.
Not really. Much of the disagreement in this thread stems from a lack of common definitions.
A
country is defined by geographic territory.
A
nation generally refers to an ethnic group, common culture or identity group.
A
state is a system of organized government that exists within a defined territory (country).
A
nation-state is a form of state which exists to protect the sovereign interests of a specific nation. The driving principle of the nation-state is the protection of national identity.
The grand fear is that the wave of brown men from the south will lead to such an erosion of our national identity....that the nation-state will no longer exist in the way we know it. The nation-state's mission will get redirected...to protect alien interests....new interests...the interests of the emerging nation formed from the remnants of the old one.
So the real trick will be in preserving the pieces of our national identity that we find indispensable, while absorbing the beneficial and enriching new pieces brought in by immigrants (illegal or not). We all agree that hot dogs and apple pie are Americana....but they didn't start that way did they? They started as german sausages and dutch/english deserts. How much Italian cuisine does this nation-state devour? Pizza as we know is a decidely American spin on an Italian food....this list goes on and on.
I think the borders are fine as is....the real issue is that we aren't diligent enough in requiring those who cross them to jump in the melting pot and melt. Instead we see the rise of the
enclave. Distance from your homeland becomes less and less significant when you can phone, email, videomail, and fly home.
