I don't necessarily predict the disintegration. I'm pointing out that the idea of blaming Trump for it is temporally silly. It's an ongoing process that didn't start three weeks ago, and even trying to backdate it to Trump's candidacy would A: be insufficient to explain anything anyhow and B: have to explain how Trump somehow knocked over the EU despite hardly saying a word about it during his campaign.

But as for everything being fine and dandy, when you get to the point that you've got sub-polities not only seriously talking about secession, but actually doing it, no, that polity is not in good health.

Yes, that fully applies to the US.
