That's what we have been doing . . . take Peru, Panama, and Columbia, for example. Yet the usualy suspects (not speaking of you, specifically) still complain.
Just observing that there is no apparent preference for bilateral deals over multilateral, on the other side of the argument. The deals are just "bad," as the sloganeering suggests.
I don’t care how multi-lateral it is if it is made by our elected representatives, can be revoked and or enforced or modified by our representatives, and does not give away these authorities to any other body. In other words, if europe wants to complain about Boeing, they come to us and complain. And we decide if they have validity, not any other body.
The other caveats are that we the people insist to our elected officials that they do not offer anything resembling free trade to our enemies, and are quick to punish malfeasance.
