For reference, here is a map of the territory that Persia must hold to complete this challenge.
With a POD of any point in history, is there any possible scenario (no matter how unlikely) in which a Persian polity with the borders pictured above can exist by the modern day?
What impact would such a state have on geopolitics? How do you think it's culture would develop? How would it handle nationalism? Do you see it becoming a thriving multicultural democracy with a high standard of living, an oppressive dictatorship teetering on the edge of collapse, or something else entirely? I'm very interested in everyone's thoughts on the matter.
