EU Pressures Turkey on Kurdistan Incursion
This could actually keep the Turks out of Kurdistan.
Membership in the EU has been long coveted by Turkey and has been pushed by Prime Minister Erdogan's party. They have used it as a way to show that they are not trying to Islamicize Turkey.
Even this pressure won't work for long if the PKK is still allowed to attack Turkey from a safe haven in Northern Iraq. Unfortunately, no one involved seems to have the ability or will to take on that challenge in the near term.
