Iran Moves Against PJAK in Iraq
The Iranian Revolutionary Guard's most recent campaign of shelling Kurdish villages in northern Iraq, which allegedly targeted members of the outlawed Kurdish opposition group the Party for Freedom and Life in Kurdistan (PJAK), eventually culminated with Iranian troops entering Iraqi Kurdish territory on August 23. According to Iraqi TV Channel al- Sharqiya on August 24, the most recent bombardments by Revolutionary Guard commandos (Pasdaran) led to the evacuation of more than 10,000 Kurds from their villages in the Pishar, Penjwin, Khurmal, Hajj Umaran and Qandil mountain range areas in the Iraqi governorates of Arbil and Sulaymaniyah.

The Pasdaran's hunt for PJAK fighters and activists comes at a critical juncture in Iran's foreign relations and domestic politics. The Iranian government is increasingly isolated internationally over the nuclear issue as well as faces widespread domestic dissent over economic mismanagement, increased political repression and President Mahmoud Ahmadinejad's foreign policy track record. Far from fulfilling his election promises of ending the country's crony capitalist structures and corruption and thus actually catering to those who had voted for him, Ahmadinejad maintained the economic and political status quo of the country and brought the Pasdaran closer to the government than any other president has done before him. Far from only representing an elite military unit, the Pasdaran now constitute a significant political and economic power in Iran, with an estimated control of more than $12 billion in business, construction and energy ventures.

While sporadic violence in the Kurdish-populated provinces of Iran is nothing new, the Pasdaran's most recent incursion into Iraqi territory, which according to a Kurdish official destroyed several villages, demonstrates the top brass and elite's willingness to defend the integrity of Iran's central government at all costs....
