I couldn’t pass this up. Jonathan Chait explains the nub of the distinction:
Here we learn that the anonymous quotes coming out of the White House are invented “so-called leaks” by the hostile reporters of the “Fake News Media.” At the same time, Trump denounces the leakers as “cowards” and “traitors.”
“Doublethink,” as George Orwell wrote, “means the power of holding two contradictory beliefs in one’s mind simultaneously, and accepting both of them.” Even Big Brother had enough respect for his audience to insist that they had always been at war with Oceania, or whoever they were at war with at the moment. You didn’t see Big Brother calling Oceania his great ally and enemy in consecutive sentences.
