Since 2016, when President Recep Tayyip Erdoğan survived a coup attempt, the Turkish leader has added a military edge to his foreign policy. Turkey’s subsequent interventions in Syria and Libya and support for Azerbaijan in its mid-2020 war with Armenia over Nagorno-Karabakh have paid dividends for Erdoğan, not only in those conflicts but also at home, shoring up his nationalist support. Ankara’s activism abroad has, however, unnerved not just rivals, but also some of Turkey’s allies, particularly Western powers already troubled by Erdoğan’s domestic policies and relations with Russia. To mitigate the fallout, Ankara has sought to smoothe ruffled feathers in the West. But even if Turkey and its Western allies can put some of their differences behind them, their divergent interests and worldviews suggest that tension and mistrust will persist.
