On January 20, 2018, Turkey launched Operation "Olive Branch" and on October 9, 2019, Operation "Spring of Peace" in northern Syria, violating its territorial integrity and military entry into the country. Also, these attacks continue in a scattered manner. According to Turkish officials, the operation was carried out to eliminate the terror of terrorism and self-defense, given that the use of force in international relations today is prohibited by international law and the UN Charter, this article examines the legitimacy of the use of force by Turkey and examines the behavior, goals and feedback resulting from its actions by citing the principles and rules of International law as well as some international jurisprudence, determines that Turkish government has violated the important principle of the prohibition of the use of force which is explicitly stated in paragraph 4 of Article 2 of the Charter, and the reasons given by the authorities of that government, including the fight against terrorism and legitimate defense, cannot justify a violation of this fundamental rule.
