There was that esoteric nazi true anon talked about who when informed of Hitler's death while on assignment in Turkey, walked into the Bosporus and drowned himself

as for larger diplomacy

During World War II, Turkey maintained diplomatic relations with Germany until August 1944. The German–Turkish Treaty of Friendship was signed on 18 June 1941. In October 1941, the "Clodius Agreement" (named after the German negotiator, Dr. Carl August Clodius) was achieved, whereby Turkey would export up 45,000 tons of chromite ore to Germany in 1941–1942, and 90,000 tons of the mineral in each of 1943 and 1944, contingent on Germany's supplies of military equipment to Turkey. The Germans provided as many as 117 railway locomotives and 1,250 freight rail cars to transport the ore. In an attempt to prevent the supply of this strategic mineral to Germany, the United States and the United Kingdom went on a spree of what was termed "preclusive buying," buying out Turkish chromite even if they did not need so much of it. As a part of the "package deal," the Anglo-Americans bought Turkish dried fruit and tobacco as well.

Seems they had little problem with them, and in autum of 1941 the nazis proclaimed Turks to be "honorary Aryans" I kid you not. In an attempt to get Turkish soviet citizens on their side. Given the number of central asian communists with nazi kill counts in triple digits you can guess how that worked out
