If the Prime Minister makes a single public comment that isn't at the 60,000 ft level in these negotiations, Tim, I think that will be a massive mistake.  This isn't the time to be playing politics for folks who want the PM to "show" them something.  If NAFTA goes away without a decent replacement, the disruption in our economy is going to severely erode the tax base, the value of our retirement savings and the value of pension plan and insurance fund holdings.  Those will have real costs to real people in this country.  Whatever you want to be "shown" is of very little importance right now.
