The recent interim nuclear agreement between Iran and the so-called P5-plus-1 countries, led by the United States, has provoked unprecedented criticism of U.S. policy from two of its strongest Mideast allies: Israel and Saudi Arabia.

Israeli Prime Minister Benjamin Netanyahu has called on his ministers and his supporters in the U.S. to lobby Congress to oppose the agreement. Meanwhile, Saudi officials have accused the U.S. of selling out its allies for little security in return.

The apparent coincidence of Israeli and Saudi interests over Iran has fueled media reports that the two countries are coordinating strategies to confront the Islamic Republic. Some suggest that Saudi Arabia will open its air space to assist an Israeli attack. Although such coordination would undoubtedly be covert, and would not prevent Riyadh from subsequently criticizing Israel's military action, it would serve both countries' national interests.
