NAFTA 2.0 is with Mexico and Canada, not Central America. Sanctions fail to work all the time and will fail in this specific circumstance. Make conditions worse in their country and the illegals and asylum seekers will not only not stop, they will step it up. Central America has no desire to cut off remittances and couldn't stop folks from leaving even if they wanted to. Furthermore, we're not the only country in the world that Central America can trade with.
