For Trump it is all one giant negotiation where it is important for him to be seen as a winner. None of the issues are separated from others. Trump has no particular beliefs other than winning and others acknowledging he is winning. If you think soft wood, dairy and NAFTA as a whole are not connected to Canada abysmal military spending and it's trend, you are Sally mistaken. May be Trudeau is playing is cards close to the best, but the recent news that military spending looks like it is going even lower than Harriet's previous post war  % of GDP low, is going to make that a scorching hot negative that affects everything else. Can you imagine someone whispering in Trump's ear " Canada's military spending is projected to FALL to 0.88%, yes that is ZERO POINT EIGHT EIGHT %.. And  do you think he gives a crap about how effective we claim our spending is? He didn't care who the best pound for pound fighter is.

It is not hard to figure out Trump, and what is effective cannot be ignored.
