What were Turko-German relations like during the Second World War, especially during and after the invasion of Greece?

With Germany and the Ottomans being allies in WW1, did the two nations maintain friendly relations during the Second World War? Did Turkey ever consider abandoning neutrality and joining the Axis Powers? You would think that Hitler’s racist ideology spoke against that, but I was wondering whether Turkey played with the idea of joining the war against Greece, considering the historical animosity between the two states.


A very good source for this issue is the book " The Evasive Neutral: Germany, Britain and the Quest for a Turkish Alliance in the Second World War", by Frank Weber
