Mercantilism is certainly what we have today, with much of the world exporting to one perennial importer. Perhaps Trump means to reverse that state of affairs (i.e., make the U.S. mercantilist), which I surmise from your comment that you think would be bad (certainly I think it would be bad!), or perhaps he means to not have mercantilism at all, which I surmise you think would be good.
