During the conflict Ankara pressured the U.S. into subduing PKK training camps in northern Iraq. The U.S. remained reluctant due to northern Iraq's relative stability compared to the rest of the country. On October 17, 2007, the Turkish Parliament voted in favour of allowing the Turkish Armed Forces to take military action against the PKK based in northern Iraq. In response, Bush stated that he did not believe it was in Turkey's interests to send troops into Iraq. Operation Sun was executed 21 – 29 February 2008.
