first of all, i hate the arabist mollahs as much as anybody, but i have to disagree with you about the caspian:
50% share is nonsense, even when it was just USSR and Iran it wasn't 50% (why would it be, USSR was huge and had like 90% of the border of the caspian but they would accept 50%?)
my understanding is the split of the seabed will be negotiated between iran-kazakh/turkmenistan, but iran is likely to end up with 11-13% (which corresponds with its share of the border of the caspian).
bad news is the oil/gas is not in the south of the sea, and the water is deeper there - that is geographical reality that the shah/mollahs/mossadegh can do nothing about!
reality is there are 5 sovereign states and the geography of it is not in iran's favour, there is not much iran can do about it.
