This American has to state that the problem is Trump.  He appoints a Trade Representative who hasn't helped negotiate a trade deal since 1983.  Canada and Mexico send their best, so now the "Tin Man" is throwing "Twitter Darts".  

I have no problem with NAFTA and how it is benefited all three countries.  Certainly it is now time for a constructive review, but not, in true Trumian fashion, turning over the card table, throwing the cards in the air and going home.  He's had a bad seven months and has accomplished nothing but setting the world against him.  Hang in there, we'll all survive., hopefully, without Trump and the sooner the better.
