I don’t think I can overstate how incredibly damaging to the US’s ability to negotiate anything, this constant changing/altering/reneging/tearing-up of deals is. Any state or organisation that fails to treat the USA as anything other than a bad-faith actor, is doing themselves and their constituents a great disservice.

I can’t imagine what (and how long) it might take for the USA to regain any credibility as a reliable party to negotiate anything with.
