Why? I thought about this. Has either of those countries said that would happen?
It doesnt come at the cost of thier nation. With the proper foreign policy this could surely happen. The problem we have is that all to often people on differing sides of an issue, they spend less time talking to those who disagree and more time talking ABOUT them.

A peaceful co-exsistance? Why is that so hard to swallow? What perceived threat would Iran and Turkey have? Legitamate, independant government in Kurdistan is probably, and ultimately is in the best interests of the involved parties.

Groups like the PPK become obsolete and peace breaks out when ethnic groups that have been long supressed, that should have had full self determination a long time ago.
