Friend and Foe: Russia–Turkey relations before and after the war in Ukraine

The interaction between Russia and Turkey since 2015 suggests a new quality in foreign affairs combining tactical alliance and strategic competition. The Russian invasion of Ukraine did not change this. By studying the cases of Syria, Libya, and Nagorno-Karabakh, we observe not only elements of geopolitical competition and cooperation but also that the combination of the two contradictory approaches in foreign affairs created new opportunities beneficial to the two sides. Russian-Turkish interactions are a unique case study in international relations and are conditioned by their geopolitical competition with the west, a fact that the war in Ukraine did not alter.
