After President Trump signed the new NAFTA agreement I thought, Trump got that one right – but then, before the ink dried, Trump erupted, twice, tweeting he hoped Michael Cohen would spend a long time in jail and that he and the President Xi of China were “the only two people who can bring about massive and very productive change.”

A slam. And a boast.

By now, it’s an old story. President Trump does something right and feelings of goodwill stir but then, in the next breath, Trump fouls his nest then the goodwill vanishes and the handwriting on the wall says: Donald Trump is his own worst enemy.
