excuse me but you are wrong
3) Join all the Kurdish areas in one state. Given the lack of clear ethnic borders you'll end up with significant Kurdish minorities outside of it and/or non-Kurdish minorities in it.
The ethnic minority Kurds would not want to be outside of their country. Let them all be united and boot all no-Kurds out, back to where they belong.
4) Create a something-Kurdish federation, as I proposed, so that you can ignore the lack of at least one clear ethnic border. In this case it was the Arab-Kurdish one. If you're willing to detach part of Anatolia to create a Turco-Kurdish federation, I'm not opposed.[/quote]
Ethnically homogenoeus states are the type of entities that provoke the least headaches, regardless of how this is achieved. The relief after it is all going to be over ending in a peaceful solution will be worth all the headaches that you will have been put through in the process of their creation.
