This article is aimed at scrutinizing Saudi Arabia’s new policy toward Iran in the Middle East. While King Salman’s ascendance to power brought a new leaf to Iran-Saudi relations, Mohammad bin Salman’s approach has led to a trend of continued escalation between the two countries. And yet, that is not the whole story. The change of leadership in Saudi Arabia came alongside shifts in the regional balance of power, which, coupled with Trump’s presidency, created a momentum for an active – and opportunistic – Riyadh in the Middle East. Accordingly, there has been a growing focus on Iran’s regional role on the part of Saudi Arabia. The defeat of the Islamic State (ISIS) and the Syrian opposition, the regaining of control by Syrian and Iraqi governments over their territories and the continuation of the Yemeni war without any light at the end of the tunnel have all driven Riyadh to see its rival’s position as having been strengthened and its own weakened. Therefore, Riyadh came up with a counter-Iran policy aimed at controlling and, ideally, reversing that regional trend.
