Turkey's Extraterritorial Use of Force against Armed Non-State Actors

Abstract

AbstractThe use of force in foreign territories has been contained in the Constitution of the Republic of Turkey, with the authorisation of the Grand National Assembly of Turkey, in ‘cases deemed legitimate by international law’ and where required by international treaties to which Turkey is a party. Yet Turkey's extraterritorial use of force against armed non-state actors lead to the most important question of identifying the circumstances under which the Turkish authorities have long justified military intervention in foreign territories. This article aims to assess whether Turkey's use of force and alleged extraterritorial self-defence contravenes international law. In order to address how Turkey interprets the right to use armed force and the right of self-defence, and to bring clarity to the state's approach to international law on the use of force (jus ad bellum), the article explores Turkey's practice based on the assessment of the Turkish military intervention in Syria, in line with both bilateral security or defence treaties to which Turkey is a party and the use of force in self-defence. The aim is to determine whether Turkey's justifications are compatible with the jus ad bellum criteria.
