Some people may see the leak that shows the Saudis want us to bomb Iran, and say "AHA! See? We should bomb Iran."
But Mark Kleiman points out:
"What could be better, from a Saudi viewpoint, than war between the U.S. and Iran? Note that the Saudis (and our other Arab quasi-friends) are willing to fight Iran to the last American. They have no interest whatever in doing anything themselves."
Indeed. We would weaken Saudi Arabia's greatest regional rival while simultaneously causing the price of oil to skyrocket.
Interestingly, when we invaded Iraq in 2003, who was the greatest beneficiary? Why, it was Iran! We destroyed Iran's greatest enemy and rival while simultaneously increasing the price of oil by shrinking the supply as Iraq's wells went offline. Of course, many people said that destroying Iraq would send Iran "a message" but things didn't quite work out that way - it has been the opposite.
Maybe we should let the people in the Middle East handle their own problems?
