The decision by three Arab states to make peace with Israel can be credited both to efforts by the Trump administration and the recognition by these Sunni states that their security would improve against the ongoing threats they face from Turkey and Iran.
Iran and its proxies interfere with Arab states while promoting their Shi’ite revolutionary ideology; likewise, Turkey pushes its Sunni revolutionary ideology of the Muslim Brotherhood throughout the region.
Turkey and Iran look to overthrow the Sunni Arab states that do not align with them, such as Saudi Arabia and other Gulf states. The normalization deals between the United Arab Emirates, Bahrain and Sudan have greatly upset Turkey and Iran, which ideologically view Israel as the enemy.
“Iran is a tactical enemy for the Gulf states because the regime is controlled by Shi’ite fanatics who want to destroy the Sunni regimes in the Gulf,” Harold Rhode, a longtime former adviser on Islamic affairs in the U.S. Defense Department of Defense who was in Iran during the early months of the Iranian Islamic Revolution, told JNS.
