The title of this article is misguided. "NAFTA’s auto rules must be negotiated on fact, not fiction"

It is fiction to believe Trump want to negotiate NAFTA. He wants to KILL IT! Negotiation is just a plot, a game to dig some issues for Trump to blame for exiting it.

Trump ideology is without NAFTA rules on the U.S. he can proceed to fully control import/export, impose tariff as he sees fit, pass laws controlling factories and employment in the U.S. He can claim success on his promise. 

But without NAFTA the U.S. economy will contract, there will be trade wars, jobs will be less. This is not his concern. He will blame others when this happen. Trump only concern is to prove he can impose his ideology. 

Trump's ideology is anti free trade, anti capitalism, anti free market. HE will dictate how things work. HE will always win. 'Totally" of course. There is a word for this ideology. It is called fascist dictatorship.
