underway in Britian since they self destructed with Brexit. Bigly. Banks and others already moving out, perhaps so much that even a full fledged reversal of Brexit won't undo all the damage. And they don't seem on a path to an orderly exit, so a crash out seems increasingly likely to me, and they will probably be far too busy limiting the damage to themselves to be much threat to anyone else.

Brexit should be a clear, easily understood message for all Americans considering voting for Trump again, about the damage brought by populist nationalist policies which promise a return to a past that never existed.
