After several years of rapprochement brokered by the Egyptian Islamic Jihad, the Muslim Brotherhood seems about to renew its traditional enmity toward the ayatollahs.
In Egypt, the Brotherhood is firmly entrenched and poised to sweep the next elections. As such, it has no need for Iranian money, and will resent Iranian influence in southern Egypt and Sinai. The Brotherhood is on the verge of leading the government, and the last thing it wants now is Iran influencing Egypt through Bedouins and small terrorist groups.
In Syria, the Brotherhood operates against Assad despite Iran’s objections. The rift is so great that Iran blames Saudi Arabia for inciting the Brotherhood.
A supranational Sunni organization, the Muslim Brotherhood may become the largest and most influential opponent of Iran’s regional hegemony.
