If Trump declares that the U.S. is laying claim to all of the green cheese on the moon — say, to lower the price of dairy groceries — the news media should not respond with fact-finding articles with headlines like “How Much Cheese Is on the Moon?” They should respond with headlines like “How Many Marbles Are Left in Trump’s Dementia-Addled Head?” But threatening to take Greenland by military force is nuttier than laying claim to the moon’s cheese. Laying claim to non-existent green cheese wouldn’t trigger a shooting war that blows apart the most powerful alliance in military history.
