Iraq has told Erdogan, that if their troops don't leave Iraq, it could turn into a regional war. Motive behind Turkeys move is-
"In northern Syria, where Turkey is backing rebels fighting Islamic State, Ankara has warned that Kurdish militias are "filling the vacuum" left by Islamic State. Fearing that this will boost the Kurdish rebellion across the border in southeast Turkey, it has threatened to "cleanse" them."
Just what the area needs, is more war,lol
