I've studied the history for a project on the life of Ataturk. There are many interpretations but one set of facts, and the fact of it is that turkey was Hitler's number one trading partner in spite of petitions by the Allies. The further fact is that turkey reversed its position when the writing was clearly on the wall in order to get a shot at charter status in the UN. Those are the facts and facts are, by definition, immutable.
Another fact, courtesy of declassified OSS files, is that the OSS and the British identified 1500 Abwehr (German) agents to the Turkish government, who controlled, imprisoned, or otherwise neutralized 800 of them.
