That makes sense. I don't fully understand the history behind the Durand Line, but it seems like it had more to do with separating Russian and British interests, and it just persisted without any formal ratification by the states that are there today.

Do you think the rather narrow, eastward reaching salient that would be created would become a problem for Iran. It would give them a couple of new neighbors. How well do they currently get along with Uzbekistan and Tajikistan?
