Saudi Arabia does not have a formal treaty of alliance with the United States — meaning there is no piece of paper obligating the US to do anything whatsoever in response to an attack against Saudi Arabia. And while the US has been intimately involved in the Saudi oil industry going back to the 1930s, nobody has ever claimed there is a deep connection grounded in values between our two countries.
But the Saudi royal family does seem to have a special relationship with Trump, who has repeatedly bucked bipartisan congressional majorities to back the Kingdom on topics ranging from its disastrous war in Yemen to the murder of Jamal Khashoggi.
It’s a fishy situation that naturally raises questions about Trump’s personal financial relationships with Persian Gulf monarchies — questions he and his allies in Congress have been successfully stonewalling for years.
