Suppose that somehow Iran becomes a free country of some kind in the late 70s/early 80s with genuine popular representation on at least some level. What does the situation look like when the USSR falls? Would a free, more prosperous Iran try to regain its old territories in Azerbaijan, Turkmeistan, Uzbekistan, Tajikistan, and possibly elsewhere? Does Iraq mind its own business or does war still occur? And what would it look like today?
