In natural law, no.
In U.S. law however, there is no right to -legal- uniateral secession.

I agree. It was also illegal to secede from Britain. It was also illegal when Texas seceded from Mexico.
Either you beleive that people are endowed by our creator with certain inalienble rights, which includes the right to self government, or you don't. I do. You don't.
I am a Yankee. I am not saying that "The south was right" or anything like that. They were slaveholders. However the fact that it was "illegal" to secede is meaningless.
