Trump once made it clear that a key part of his philosophy of life was, if he felt scorned or laughed at, to get even. Get Even!

That explains the line about the world laughing at the USA and how his pulling out will stop them laughing. It's all about Trump. It's not even about the Art of the Deal, as the Paris Accord was a mega-deal.

Trump was embarrassed in his European tour and so he has decided to GET EVEN. Whatever the World wants, they can't have. So there!

Make America Marginal Again. Or Mama.
