By going after both at the same time while thumbing their [Kurdish] nose at the central government is an incredibly shortsighted plan.
***My understanding is that the PKK has been operating for decades against Turkey. Only recently have the Kurds been operating in Iran, due to OUR prompting and furtive assistance. They are not thumbing their noses at any central guvmint, the central guvmint is simply having trouble forming a coherent entity. The only thing shortsighted that I see the Kurds doing is, well, TRUSTING US. After all, we already betrayed them once & Saddam gassed them.
You're not wrong about the PKK. My comment was about their timing --- assuming the Kurdish political structure has any influence over them at all.

They've made some sketchy oil deals outside the authority of the central government. Given the economics of Iraq, there is no better way to thumb one's nose at their government. It's kinda like the death match for influence going on in Basra right now... Petty power grabs are costing lives.
