The Turkish parliament voted on Thursday (298-98) to approve military operations against IS in Iraq and Syria. This sets the legal framework for any Turkish military involvement in Iraq or Syria, and for the potential use of Turkish bases by foreign troops. Turkey has been reluctant to work with the coalition, but recent developments have made them change their mind. Turkey has received an unprecedented amount of refugees fleeing the crisis and now shares an extended border with IS, who has attacked border towns. This is a step in the right direction for Turkey, but I would not expect any immediate action outside of protecting their borders.
