Mulroney's observations on Trump's evolving view on NAFTA were interesting. 

It occurs to me that, simple trade aside, the US/ Mexico issues are going to be long term and will not be resolved by Trump's administration. One of the unspoken benefits to the US o is that NAFTA  is raising the living standard of the average Mexican strongly. Illegal immigrants from Mexico have traditionally been searching for meaningful employment, and NAFTA has moved those opportunities closer to home. NAFTA is therefore, in fact, an effective partner in the battle against illegal immigration from Mexico, and will be into the foreseeable future.
