In just a few months since returning to the White House, President Donald Trump has claimed remarkable powers to reshape global trade and has erected some huge barriers to imports into the United States.
Trump has done all of that while repeatedly revealing how little he knows about what he imagines he can design. By now, it is obvious that Trump does not understand what trade deficits are, does not know that Americans bear the cost of his tariffs, and does not comprehend how American manufacturing is dependent on global supply chains.
But what if the problem actually runs deeper than that? What if the man who has been entrusted by the Republican Party to reshape huge swaths of the national economy and the flow of global trade is suffering from the same sort of cognitive decline that marked Joe Biden's time in office?
