Our so-called "biggest trading partners" were just mooching off of the "USA teat" at the expense of the USA citizenry. How do you suppose they can afford their so-called "free healthcare" (and related) policies? It's quite easy when you suckle off of someone else and don't have to pay for your own defense.
Trump is making the USA great again. Trump is making our so-called "biggest trade partners" "pay their fair share" (as you would call it). If they get BIG MAD about no longer being able to freeload off of the USA citizenry, then so be it. Good riddance. We don't need them one bit.
Their only option is to run to China, which they have now been doing ever since Daddy Trump cut them off from being freeloaders. They are doing so to their own demise. They are following the Church of Green to their own demise, too, and China is aware of it and they are completely bending Canada and Europe over furniture due to Canada and Europe's own self-imposed limitations on energy generation.
Lies. President Trump has been making all sorts of deals with all sorts of nations.
