I doubt US obsession will stop being other county's pastime just because Trump is gone.
It won't stop, but most of us will be happy to focus on other train wrecks for a change.
Seriously, though, I remember being amused by the apparent illiteracy of Bush Jr and pleased with the marked improvement when Obama took over, but with both of them, I had no problems ignoring the US unless the drama affected the rest of the world. We have our own problems to worry about, so feel free to keep yours.
