It is not surprising that Mr. Martin, an ardent left-wing progressive, calls Canada's NAFTA demands "mostly reasonable".  By contrast, Andrew Coyne views them very differently. His opinion is that the prime minister has outlined demands that are akin to "a feminist-aboriginal rights manifesto against global warming", which can easily be seen as completely unacceptable to the Trump administration and therefore are being made because "Justin Trudeau and his advisers have concluded the talks have no chance of succeeding, and are already preparing for their demise".
I agree with Mr. Coyne's assessment.
