This isn't just a U.S. vs. Mexico dispute here. It also involves major U.S. trucking companies (who support the plan to allow Mexican trucks into the U.S.) vs. independent owner-operators (who are adamantly opposed to it).

What sometimes gets lost in the shuffle here is that the cross-border trucking program was a specific provision of NAFTA -- which means the U.S. really isn't on solid legal grounds to prevent its implementation.

That is not true. NAFTA is a law not a treaty. Congress can alter or abolish any previous law buy passing a new one. It can also effectively neuter a previously passed law by refusing to fund its enforcement.
