DURHAM – This year, Islamist politics has faced massive setbacks in two major predominantly Muslim countries: Egypt and Turkey. But it is too soon to write political Islam off as a capable participant – even a leading force – in a pluralist democracy.Just one year after the Muslim Brotherhood’s Mohamed Morsi became Egypt’s first elected president, millions of Egyptians took to the street, triggering the military coup that ousted him. Morsi’s political incompetence and lack of vision in the face of economic collapse would have been enough to diminish support for his government.  But his rejection of pluralism and pursuit of an Islamic dictatorship, exemplified by his efforts to centralize power in the hands of the Brothers and place himself beyond the review of Egypt’s judiciary, proved to be his undoing.Similarly, Turkey’s Prime Minister Recep Tayyip Erdoğan, of the Justice and Development Party (AKP), has taken to governing in a way that is unraveling a decade of progress, one marked by economic dynamism, rapid growth, and the subordination of the armed forces to civilian control. The Erdoğan government’s recent brutal crackdown on popular protests against planned construction in Istanbul’s Taksim Gezi Park made Turkey look like a one-party dictatorship. To make things worse, Erdoğan then spent weeks subverting pluralism through polarizing speeches that stigmatized Turks who do not share his social conservatism or subscribe to his particular interpretation of Islam.Given that Egypt and Turkey are two of the three most populous countries of Islam’s historic core (the third is theocratic Iran), one might infer that their ongoing difficulties have destroyed any prospect of reconciling political Islam with pluralist democracy. But the two countries’ situations include fundamental differences, as do political Islam’s prospects for renewal.In Egypt, the economic challenges are so dire, and traditions of consensual governance so shallow, that it may be impossible for any party to rule democratically in the foreseeable future, let alone the Muslim Brotherhood, which would have to reinvent itself completely. And non-Islamists are even less likely to trust the hardline Salafist Nour Party – the Islamist party that participated in Morsi’s ouster – to uphold democratic principles.In contrast, Turkey’s AKP still stands a chance of re-legitimizing itself in the eyes of offended constituencies, because its retreat from pluralism is strongly identified with Erdoğan himself. In fact, some AKP heavyweights, including Erdoğan’s longtime associate, President Abdullah Gül, believe that he badly mismanaged the recent protests.By replacing Erdoğan as party leader, the AKP could dissociate itself from his Islamization campaign and rehabilitate its potential as a democratic political force. Many AKP constituencies are wary of cultural conflict, if only because it threatens their economic interests. Hence, such a move would probably be enough to restore much of the AKP’s lost support and to calm opponents who fear that their personal freedoms will continue to erode under its governance.An opportunity to replace Erdoğan will arise next year, when Gül’s term expires. Erdoğan wants to deny Gül a second term, taking his place under an amended constitution that would transfer full executive authority to the president. By denying his wish, AKP parliamentarians would weaken Erdoğan’s standing, possibly enabling the party to push him aside.If this proves insufficient to drive Erdoğan from power, the arrival of his self-imposed prime ministerial term limit in 2015 will allow the AKP Executive Council to force him to retire simply by holding him to his word. With the AKP having demonstrated its disapproval of Erdoğan’s undemocratic behavior, its new leadership could begin to rebuild its legitimacy as a party that respects minority rights.To keep it from losing its way again, the AKP must also address the root cause of Erdoğan’s metamorphosis into an intolerant autocrat. Early in Erdoğan’s premiership, he was restrained by the president, the judiciary, and the military, which were all committed to upholding the secularism enshrined in Turkey’s constitution. As recently as 2008, Turkey’s highest court considered shutting down the AKP for violating that principle.Timur Kuran is Professor of Economics and Political Science at Duke University and the author of The Long Divergence: How Islamic Law Held Back the Middle East.Copyright: Project Syndicate
