Ironically, he has finally pushed certain so called Pro Palestinian countries in the region to finally lay their cards on the table and form a coalition to resist this.
It's scary, but Trump is in a race against time, he has approximately 12 months before he has to start campaigning for the midterms. The more his base learns about this the more turn against him.
