I see that economics is not your strong suit.
I'm not seeing a lot of economic genius around here, but this is what Trump said about NAFTA:
"We have large trade deficits with Mexico and Canada. NAFTA, which is under renegotiation right now, has been a bad deal for U.S.A. Massive relocation of companies & jobs. Tariffs on Steel and Aluminum will only come off if new & fair NAFTA agreement is signed."
Apparently, he thinks it could use some improvement.
