National Security

Open Borders

Over the past few days, I’ve been watching with interest on Twitter as Doug Mataconis and Jason Pye have been moaning about the new immigration law in Arizona. Now, I grant it’s a bad law from a civil liberties perspective. I’ve seen to much of policing from the inside to trust police not to run a truck through any ambiguities that they find in the law.

But some of the links they’ve posted seem a bit overdone. For instance, one of them linked to an article that implied that there’s a white supremacist behind the movement to pass the law. But what really caught my eye was a link to an article that gave all the standard libertarian reasons for having open immigration.

There was only one thing wrong with the article. It made all sorts of arguments about natural rights and economics, but nowhere did it address national security.

So, I guess my question is this: If you are going to argue for opening the borders, how will you go about doing so in a world of hostile nation-states, whose citizens may wish to do us harm? Clearly, the framers gave some thought to the issue, as they gave Congress plenary power to regulate immigration.

So, even granting that the rights-based and economic arguments are correct, which, mainly, I do, I still would like to know how you would address the security implications of open borders in a hostile world.

Surely, our agreement on the general principles of liberty don’t require us to commit seppuku by allowing hostile foreign powers to take advantage of them, do they?
