“These gates will open and these Isis members who have started to be sent to you will continue to be sent. Then you can take care of your own problem” — Erdogan

To understand Erdogan's actions you only need to know two things.

  1. Turks hate Kurds and Kurds hate Turks, the current war has driven a huge amount of Kurdish refugees into Turkey. These people hate the Turkish state and stage frequent terrorist attacks.

  2. Syrian refugees who mostly landed in Turkey hate Erdogan and love Ataturk, and as such vote overwhelmingly for Kemalist parties who are Erdogan's opposition.
