Personally, i would like to see the south gaining autonomy like the kurdish north. The north has really been developing itself without the need of Baghdads help. The south has been subjected to massacres due to the previous governments.

However it must not become effectively an iranian puppet. This will be the most probable case since the most powerful leaders in sourthern Iraq are the Hakim family who spent like 30 years in Iran - Ammar Hakim the 36yr old spent 30 years of his life in iran.
