Turkey is among a league of revisionist powers who are challenging the world order. Erdogan and his Islamist movement have aimed to create the "New Turkey", preparing for a future that is less dependent on Western treaty allies and with an alliance structure of its own.This book is about the political ideas driving Turkey's regime change and foreign policy. It de-exceptionalizes Turkish politics, arguing that the "New Turkey" is part of a global trend of far-right nationalist movements like that of Donald Trump in the United States or Narendra Modi in India. In particular, the book reveals how far-right nationalist strands in Turkey have been nurtured by an existential resentment of the West, similar to those we are seeing in Russia. In tracing this resentment and its historical roots, the book invites policymakers and experts to better understand the new relationships Turkey is building with fellow revisionists including China and Russia, as well as Turkey's involvement in the wars in Syria and Ukraine and Erdogan's grand strategy for expansion. The book is based on interviews with senior politicians and civil servants from across the country's political spectrum. It also benefits from the author's personal knowledge of Turkey's far-right and Islamist traditions.
