Peshmerga
The Peshmerga (Kurdish: پێشمەرگه, romanized: Pêşmerge, lit. ''Those Who Face Death'') are the internal security forces of Kurdistan Region. According to the Constitution of Iraq, regional governments are responsible for "the establishment and organization of the internal security forces for the region such as police, security forces, and guards of the region". Other Kurdish security agencies include the Zêrevanî (gendarmerie), Asayish (security and counterterrorism service), and the Parastin û Zanyarî (intelligence agency). The Peshmerga's history dates back to the 18th century, when they began as a tribal paramilitary border guard under the Ottoman Turks and the Safavid Kurds. By the 19th century, they had evolved into a disciplined and well-trained guerrilla force.
Formally, the Peshmerga are under the command of the Ministry of Peshmerga Affairs of the Kurdistan Regional Government. In practice, however, the Peshmerga's structure is largely divided and controlled separately by the two Iraqi Kurdish political parties: the Democratic Party of Kurdistan and the Patriotic Union of Kurdistan. Though unifying and integrating the Peshmerga has been on the Kurdistan Region's public agenda since 1992, the individual forces remain divided due to factionalism, which has proved to be a major stumbling block.
Following the 2003 invasion of Iraq, the Peshmerga played a key role in helping the United States on the mission to capture deposed Iraqi president Saddam Hussein. In 2004, they captured Saudi-born Pakistani terrorist Hassan Ghul, who was operating for al-Qaeda in Iraq. Ghul was turned over to American intelligence officers shortly afterwards, and revealed the identity of several key al-Qaeda figures during his interrogation, which eventually led to the killing of Osama bin Laden in a covert American military operation in Pakistan in 2011. One year later, in 2012, Ghul was assassinated by an American drone strike in northwestern Pakistan.
