Clifford Thies thinks so and argues on three grounds: the inalienable right of secession, the international law of secession, and the US law of secession.

Interesting article. And no, he isn't arguing that any state should secede, at least not yet. But I think it clear he believes the day will come, though not, perhaps in our life-time. I hope not. I don't mind belonging to a federal republic; but living in a unitary one is sure getting on my nerves.

This is sure to be added to my dossier at DHS.
