The list of countries in the Middle East region seen lining up against Iran in the cables is significant: Saudi Arabia, Jordan, Bahrain, the United Arab Emirates, Egypt and Qatar.
A convenient summary of an article that you should definitely read in full:
The revelations, in secret memos from US embassies across the Middle East, expose behind-the-scenes pressures in the scramble to contain the Islamic Republic, which the US, Arab states and Israel suspect is close to acquiring nuclear weapons. Bombing Iranian nuclear facilities has hitherto been viewed as a desperate last resort that could ignite a far wider war.
The Saudi king was recorded as having "frequently exhorted the US to attack Iran to put an end to its nuclear weapons programme", one cable stated. "He told you [Americans] to cut off the head of the snake," the Saudi ambassador to Washington, Adel al-Jubeir said, according to a report on Abdullah's meeting with the US general David Petraeus in April 2008.
