President Trump is playing a tense poker game with Saudi Crown Prince Mohammed bin Salman. The stakes are America’s oil industry and the U.S.-Saudi alliance.
The 34-year-old prince and the president have been fast friends since Mr. Trump chose Saudi Arabia for his first foreign trip and received a lavish welcome. The president stood by the prince when he severed relations with Qatar, and again when he was accused of approving the murder of Jamal Khashoggi. But now the prince is threatening America’s oil industry, U.S. national security and Mr. Trump’s re-election prospects.
