The crown prince has a lot of leverage too, throwing some cash around before his trip (a $400 million investment in a Hollywood talent and events planning agency) with the promise of more to come.
Bin Salman was very happy that the Tuesday's meeting exceeded his expectations, which doubled the amount of investments between Saudi Arabia and the US.
In front of the cameras, it was all back-slapping, handshakes, smiles and warm words between Trump and the heir to the Saudi throne, Mohammed bin Salman, who was seeking to burnish his leadership credentials.

The news was accompanied by expressions of concern about a USA law that exposes Saudi Arabia to legal action over the 9/11 attacks, which Riyadh would dearly like to see removed.
The son of King Salman and heir to the throne will also hold separate meetings with a long roster of influential US officials, including the secretaries of defense, treasury and commerce, the Central Intelligence Agency chief and congressional leaders from both parties.

As they talked, USA senators debated a resolution seeking an end to USA support for Saudi Arabia´s campaign in Yemen's civil war. King Salman is slated to visit the United States later this year. Since then, the Saudis have been even more wary of Iran expanding its influence in the Middle East.
The 15, mostly Democratic, co-sponsors are trying for the first time to take advantage of a provision in the 1973 War Powers Act that allows any senator to introduce a resolution on whether to withdraw United States armed forces from a conflict not authorised by Congress. While the relationship between Israel and Saudi Arabia is reasonably stable right now, that could change in the future, he explained, making it risky for Israel should the Saudis pursue nuclear weapons.
