I don't have much on the Kurds and Druze,
for thr kurds: The Kurds by Mehrdad Izady
Sadly I don't have a good book for the Druze.
but I can recommend some Israeli books
Israel books: Start up nation, rise and kill first (it's about the mossad), the prime ministers, spies of no country, the weapon wizards, Moshe Dayan, the revolt (good luck finding it, it's out of print).
Don't read: from Jerusalem to Beirut. The book is shit.
Israelis tend to be very critical of themselves so you don't need Arabs telling you how bad Jews are. the Jews will just do themselves.
