Etyen Mahçupyan in Akşam writes that it is not easy to plan and execute an act of terrorism.  The needs of organization increase the likelihood that the suicide attack in Ankara had a foreign source. The purpose can be to render Turkey incapable of exerting influence in the Middle East by burying it in internal problems.  Alongside this, there can be said to exist results that are wanted when it comes to the internal politics: such as, to spread hopelessness among the public, undermine faith in the state, to paralyze the government, to create a vacuum of authority, to render internal peace impossible… We need to bear in mind that the massacre took place at a juncture when it was being said that the PKK was going to declare a cease fire, as the government was conducting operations against ISIS within the country and as the Syrian air defense system had locked on Turkish war planes.
