I don't know if you would take this as a neutral resource, but if you are interested in this subject, you may find the writings of Henry Morgenthau Sr. interesting. He was the U.S. Ambassador to the Ottoman Empire during the period when the USA was neutral in WWI. He also happened to be a friend of my great-grandfather. In particular I would recommend "I was sent to Athens" (link: https://openlibrary.org/books/OL6734490M/I_was_sent_to_Athens https://openlibrary.org/books/OL6734490M/I_was_sent_to_Athen...) and the section on the 1922 Izmir Fire.
