Over the longer-term, a more competitive and conflict-prone relationship between Russia and the West will test the foundations of recent Turkish foreign policy. It will also test Ankara’s cooperation with transatlantic partners. First, the current crisis underscores the return of hard security challenges on Turkey’s borders. Second, the crisis in relations with Russia comes at a time of considerable unease in Turkey’s relations with NATO partners, many of which are not on the same page when it comes to Syria and other questions of deep concern to Ankara. Third, and more positively, the Ukraine crisis is likely to drive NATO strategy and planning in directions Turkish strategists will prefer.
