So we just won't call it a treaty

Sounds like Newspeak to me.

Isn’t “not a treaty” basically how NAFTA was passed?

Fair enough statement, but that was very small compared to an agreement with 136 countries.
It also means that it can be repealed via reconciliation.

Yes, our system is broken. Has been for decades.

Yet it is the best in the world, and probably in history.
