Considering what is known, Trumps proposal seems to be free trade for the US, tariffs for the “Privilege” of getting foreign products on US shelves, and no willingness to negotiate for anything less.

That is my take on it as well.

He is well known to take a “zero sum game” approach to pretty much every situation. The only way he can envision him winning is to make others lose.

The concept of mutually beneficial agreements seems like something that he cannot understand or accept.
