Iraq is a federal country in a governorate system that has local councils wich is a kind of decentralisation form, all the arab governorates are considered one region under the central govt though the sunnis want these days to get their own autonomy, the other region is the autonomous kurdish region
There's a disputed region such as kirkuk wich is waiting for referendum either to join the kurdish region or stay under the central govt, however kirkuk has been now annexed by kurdistan taking advantage of the insecurity in the south and the collapse of maliki govt!
Now, somalia including puntland region is under the state building process that will come to end by 2016
This means the country will have constitution, federal states, elections etc.
The fate of mudug region depends on the federal commission!
So I guess, before 2016 there will be too disputed areas in the constitution under the federal govt not sure how large this region will be depends on the federal commission that was recently established
After 2016 this region may join other parts( according to the political process not the actual power)
The yellow one is the disputed iraqi region
