I disagree with the 75% figure. The last I saw indicated that 62% of our exports go to the US, which would put our 'exposure score' lower. A 20% tax would no doubt hurt our exports, so, I guess, if they feel that way then we will have to put a 20% tax on their imports to Canada. Since 34 States identify Canada as the most important destination of their production, I imagine they might get a little upset if we screw them like they plan to screw us.

This is just another version of a hold up. The US has been doing it for years.
