Renegotiate NAFTA and the Trans-Pacific Partnership. If Trump re-opens negotiations on NAFTA, the Mexican government would require immediately, that the United States allow Mexican trucks on its roads. That was promised in the first NAFTA agreement but withdrawn by Congress. Mexico is in much better economic shape now than when the three countries first negotiated NAFTA. For that reason, a new agreement would be worse for the United States, no matter how smart and cunning Trump's people are.
