Explaining the Decline Of Suicide Terrorism in Turkey

Since the 9/11 attacks, there has been a growing interest in the terrorism problem, in general, and the strategy of suicide bombing, in particular. Between 1996 and 2016, Turkey experienced several deadly suicide attacks by groups like the Kurdistan Workers’ Party, the Revolutionary People’s Liberation Party/Front, al-Qaeda, and the Islamic State. These attacks can be explained by individual-oriented, institutional, socio-psychological/economical/identity, and structural theories. However, a central question now is why there have been no suicide attacks since 2016—that is, until the attempted bombing of the Ministry of the Interior on October 1, 2023. This article advances five main reasons for this success: a shift in Turkey’s antiterrorism strategy, the introduction of new technologies, terror groups’ concerns about losing legitimacy among supporters, the failure of these organizations to achieve their objectives through suicide terrorism, and changes in Turkey’s external environment. The article concludes that, as the October 1 attack demonstrates, the renewal of suicide terrorism is likely, given Ankara’s sole focus on the institutional and international/structural aspects of the problem, which does not allow enough attention on individual and sociological factors.
