First, because Saudi Arabia, despite the hostility of some Arab countries to the policies of the royal court in Riyadh, will not accept that their holy land is subject to US sanctions, and therefore America will not be able to face full Arab hostility.
But the main reason why Washington fears Riyadh is that Saudi Arabia has significant investments in the technology sector in America.
Over the past few years, Saudi Arabia has been keen to reduce its dependence on oil, the technology sector, and invests, especially through the Public Investment Fund.
Riyadh is a key investor in the US technology sector.
HRH Prince Alwaleed bin Talal, the Saudi-born Saudi Crown Prince, has long held numerous investments in this sector through his Kingdom Holding Company.
These entities, and sometimes Prince Alwaleed alone, have invested in many emerging companies or major US technology groups.
According to a study by CBS Insight on Saudi investments in the technology sector in 2013 and 2018, the Saudi authorities invested more through the Public Investment Fund, especially $ 3.5 billion in Opere in mid-2016.
And Yasser Al Rumian, General Manager of the Saudi Public Investment Fund, a member of the Board of Directors of Ober Rent A Car with a driver.
However, the chairman of the board of directors of Ober Dara Khosrofshahi was among the heads of institutions who canceled their participation in the next economic summit in Riyadh.
The Saudi Public Investment Fund, particularly in the electric car industry, has invested in Tesla and its rival Lucid, while Kingdom Holding has invested in Oper's rival in North America, Levitte said.
The Saudi Public Investment Fund is also linked to the Japanese group Softbank through Softbank Vision Fund.
It has about $ 100 billion earmarked for investment mainly in the technology sector. About half of the funds come from the Public Investment Fund.
Vision Fund has also invested in self-driving vehicles such as GM's Cruze, or "Slack", a collaborative communication platform.
Prince Alwaleed also has investments in Twitter and Apple and owns 2.3 percent of Snape's parent company Snat Chat.
Saudi Arabia is also an important market for technology groups, especially with the Kingdom's technological push through Vision 2030 aimed at transforming it into a technology and tourism giant.
In May, Microsoft launched its Cloud service in Saudi Arabia in partnership with Saudi Arabia's Sahara Net and Lenovo. The US group estimated the Saudi market at 108.75 billion riyals ($ 29 billion), a figure that could be "significantly higher" due to Saudi digital transformation targets, Microsoft said in a statement.
Prince Mohammed bin Salman, the powerful man in the kingdom, made several visits to the United States, including one in the spring of 2018, where he met officials from groups such as Google and Apple.
Jeff Bezos, chairman of the board of directors of Amazon, who is interested in the Saudi market, also met. The situation seems delicate today for Pezos because at the personal level the Washington Post owns one of Khashoggi's operators.
