It's going to be a problem if the PKK doesn't withdraw its armed fighters at least. There's no love lost in terms of political concurrence, competition, between the KDP of Masoud Barzani and the PKK.
I think in the short term, they don't have a plan. I asked some Iraqi ministers myself a few weeks ago about just developing more powers for the communities like the 2005 constitution and the 2008 law of the provinces, which allows them to let them run their own show until they figure out more long-term arrangements for possible autonomy or the creation of other regions or what have you. Right now, there seems to be a remarkable lack of organization and thinking as to what the new political arrangements will be. I am quite worried about it.
