A very interesting column in Asia Times concerning the potential role of Kurdish forces based in Iraq on the future of Iran. Recent reports suggest some Kurdish fighters have infiltrated across the shared border with Iran in hopes of supporting their ethnic cousins in Iran against what remains of the regime there.
The column suggest an entire cascade of potential outcomes resulting from a significant Kurdish involvement. It could trigger a major Turkish ground offensive and possible moves by the Saudis and the Pakistanis.
At least one outcome could be the balkanization of Iran into ethnic enclaves, either freestanding or attached to neighbors.
N.B., A web search finds the following about Iran's population.
Iran's ethnic composition includes Persians (approximately 61%), Azerbaijanis (16%), Kurds (10%), Lurs (6%), and smaller groups such as Arabs, Baloch, and Turkmen, each making up about 2% of the population.

Please excuse my pun in the title, apologies to little Ms. Muffet.
