We negotiated those deals, we aren’t the victims. Now we don’t like how a deal turned out so instead of renegotiating we are throwing a temper tantrum like we weren’t the ones who suggested it in the first place. It’s embarrassing to be represented like that, and it won’t work! We will wind up weaker than we started, I hope they prove me wrong.
The u.S. didn't negotiate protectionist policies against their own exports. Can you cite a single example of this?
A more charitable explanation is that the U.S. has been all in on globalization and free trade since the 1970s and the rest of the world took a protectionist stance in response. I'm sure the rest of the world had their reasons. But the U.S. does now, too. Globalization and free trade that only substantially flows in one direction simply is not sustainable.
