Every generation wants to re-discover their world.  We (boomers) did it. It is happening again.  In many ways is time.  Trump is not a reason though.  "The Deal Maker" has no idea about the puts and takes of any agreement.  The USA has seldom won a review of its malpractices under NAFTA before the arbitration process - but they keep re-running issues.  They are BAD partners.

NAFTA is a point on a continuum.  It was preceded by decades of Canadian protectionism called "the National Policy."  That worked much better than any formal trade relationship with the USA and was hard for us to give up in favour of free trade.  

As the new generation of American trader-politicians re-invent these wheels, Canada must grin passively while aggressively getting out of the relationship with the USA.  The TPP is a far better idea for Canada.  If the USA loses all Canadian resource reserves from hydrocarbons to uranium and even softwood stumpage (FMA) they will wake up TOO LATE!

BRING IT ON!!! PLEASE
