The President of Turkey insists to be involved in the recapture of Mosul, Iraq's second largest city. Currently, Mosul is controlled by ISIS. Turkey claims it has a historical responsibility for this area, which displeases the Iraqi government. Turkey has stationed troops in both Iraq and Syria, which represents the dissolving sovereignty of countries in the area. Iraq is not the only country concerned about Turkey's actions. For almost a year, the United States has urged Turkey to respect Iraq's sovereignty. Turkey has undermined the United States's support of Kurdish forces in the Syrian conflict. Some even argue that tensions could lead to a war between Turkey and Iraq.
