The Kurdish question started to be discussed especially after the establishment of Republic of Turkey in year 1923. This problem has many different aspects, as well as sociological and political problems. PKK, the terrorist organization, constitutes another dimension of this problem. The peace process for the sustainable peace regarding with the Kurdish question and PKK took place in year 2009. This process aimed to end the PKK terrorism and to solve the Kurdish question from its roots through effective and permanent methods. However, the solution process begun in year 2009 by the AKP government in Turkey could not be resolved but it turned to a stalemate because of inconclusive and abstracts steps followed in the process, as well as the foreign difficulties. This research will examine why and how this peace process failed. This study, which includes the interviews with Isik Kansu and Osman Taney Korutürk, aims to shed some light to the resolution process in Turkey from different political and sociological perspectives, by considering discussions on the political failures, political judgement and strategic decisions.
