One answer may be due to pressure from oil-producing companies and countries, especially Saudi Arabia. How close Mr. Trump is to the Arab authorities, that’s clear.
The United States has turned away, even defending the Arab king, when he ordered the killing of the opposition journalist in Turkey. Most recently, Arab oil reserves were attacked by unmanned aircraft, and the President blamed Iran and “fumbled” that the United States was ready to fight Iran but waited to see if the Saudi side provided any conditions. The phrase “túyt” shows how important the Saudi leadership is to the President, because the United States cannot unilaterally decide this big deal if the Saudis don’t give the green light.
