I was musing recently about what possible motive Saudi Arabia could have for provoking war with Iran. Joschka Fischer suggests one answer:

As part of his agenda, MBS has also launched an aggressive new foreign policy, particularly toward Iran. The modernizers around MBS know that the revolution’s success will require breaking the power of Wahhabism by replacing it with Saudi nationalism. And in order to do that, they need a compelling enemy. Shia Iran, with which the Kingdom is competing for regional hegemony, is the ideal foil.

These domestic considerations help to explain why Saudi Arabia has thrown down the gauntlet and escalated tensions with Iran in recent months. Of course, from the Saudis’ perspective, they are merely picking up the gauntlet that Iran already threw down by interfering in Iraq, Syria, Lebanon, Bahrain, Qatar, Yemen, and other countries.

So far, the battle for regional hegemony between Saudi Arabia and Iran has been limited to proxy wars in Syria and Yemen, with disastrous humanitarian consequences. Neither side, it seems, wants a direct military conflict. And yet that outcome can hardly be ruled out, given recent developments. In the Middle East, a cold war can turn hot rather quickly.
