Placing President Trump's critics' claims into any sort of historical context got a lot harder this week. Jim Carrey defended Kathy Griffin's gory depiction of the president's severed head as evidence that comedians are the last voice of truth in U.S. politics. A German professor stated what Chancellor Angela Merkel would not: "The belief in shared values has been shattered by the Trump administration." Today we learn that the president has declared war on the planet itself. As for the universe beyond, new ripples have been discovered in space-time. The White House has refused comment.
