"The Dumbest Trade War In History"

Mr. Trump sometimes sounds as if the U.S. shouldn’t import anything at all, that America can be a perfectly closed economy making everything at home. This is called autarky, and it isn’t the world we live in, or one that we should want to live in, as Mr. Trump may soon find out…

None of this is supposed to happen under the U.S.-Mexico-Canada trade agreement that Mr. Trump negotiated and signed in his first term. The U.S. willingness to ignore its treaty obligations, even with friends, won’t make other countries eager to do deals. Maybe Mr. Trump will claim victory and pull back if he wins some token concessions. 

But if a North American trade war persists, it will qualify as one of the dumbest in history.

Autarky, by the way, was the economic policy of the Nazi Party.
