"How do you negotiate with a bully? Can you reason with an egotist who will not listen to another point of view?"

Yeah, I'd say the U.S. negotiating team has its work cut out for it, alright.  

Because that is a problem for the U.S. TEAM not necessarily Canada's team.  Because the Pres. will not be at the table--as much as he would like to be (so he could dominate, TV reality-show style.)  And, I suspect, that the U.S. team will be, to some extent, rational and fair-minded.  Well, more than the President, anyway.  So, tough darts for them.  Knowing this going in will help.

For us?  The admonition of a former U.S. President--Theodore Roosevelt--might be advisable: "Speak softly and carry a big stick."  Maybe more than one stick.  

So, question to Canadian NAFTA negotiating team: got your sticks in order?
