The USA at present and with future use of renewables, has enough energy to last for a long time without the Saudi Oil. That said, the reasons we don't tell them to stick it are at least two: 1. The Texas Refiners are set up to process heavy crude which comes from the Saudis at a discount. Guess which group, initials KB get that discount. 2. The other reason major has the initials MIC and I don;t mean the Mouse. Google oil imports for the answer.
