Actually Trump renegotiated it, called it USMCA, said it was the best trade deal in history, signed it on camera in a huge White House press event, lost the Presidency, won the Presidency, and then called it the worst deal ever and that it was signed by a stupid “past President”. Then tariffs in violation of it.
Even for Trump, that story arc is pretty wild.

It is huge, monolithic, and difficult to modularize.
It is complex.
It occasionally has runaway resource use (eg. Indexing).
