Well that makes NAFTA irrelevant! Trudeau and Pena Nieto need to press Trump to renegotiate NAFTA as soon as he is inaugurated, put him on the defensive! There is no value to a free trade agreement where one side can arbitrarily stick in tariffs and the only expected short term reaction would be retaliation - I suggest heavy tariffs on American meat and dairy products. I wonder how Brian Mulroney is going to sugar coat his hero doing things like this which are completely at odds with Mulroney's avowed love of free trade?!
