Iraqi Kurds are gaining ground thanks to United States’ air strikes in northern Iraq and support from the regular Iraqi army. On the one hand they have the decision made by the U.S., France, Germany and Great Britain to provide the Kurdish peshmerga with weapons, and on the other, the Kurdistan Workers Party (PKK) is providing logistic support to Kurdish fighters. Furthermore, the PKK’s historic leader, Abdullah Ocalan, following a letter dated 2013 in which he asked for the armed struggle to end, has reiterated a request to end all conflict with the Turkish authorities in a document signed in Imrali prison (Sea of Marmara).
