Correct. Just like the eu was good for the uk until they decided it wasn't. Except the issue of secession was settled in the affirmative there and in the negative here.

You'd be hard pressed to argue the confederacy wanted to take over the union and then impose slavery on the free states. I mean, you could make the argument, but it's more likely to me they simply wanted to leave and continue enslaving people.

I don't know how this turned into a discussion on slavery. The issue was secession. The civil war answered that us states cannot secede. Itll be interesting to see how the dynamic in the eu changes since this is a possibility there (although I'm doubtful they'd let a continental member leave).

All states have a right to leave the EU by treaty - it was inserted to defuse a previous bout of Euroscepticism that argued by analogy with the US civil war that union author a secession right was tyranny.

I can't see its use being refused: that would disintegrate the bloc. And there was no question that we (the Brits) wouldn't be allowed to, so the precedent has been set.

I would imagine a few tweaks to the Article 50 exit mechanism will be made next time the treaties are revised - there are some game theory problems in the current trigger mechanism and the timescales set down turned out to be too short in practice - but it's no longer in dispute on principle.

It was also not in dispute in the first constitution of the united states, but they just did away with that for funsies (I'm being facetious). I imagine we'll see something similar in the EU as the bloc becomes more integrated.
