Yes, I understand that. And I have read that Israel and the Kurds have very good long term relationships.
I don’t know that much about the history of the Kurds, but from what I have read, they have always had a history of being good soldiers.
They predate Islam but were conquered by Muslims and converted, but they have suffered persecution by their own for a long time.
My suspicion is the ruling Muslims felt the Kurds were a threat to their power and eliminated them. In multiple massacres.
Now they are a mixture of religions and they accept that.
By the way, the Kurds are actually an Iranian ethnic group. Not sure if you knew that. Pesh-merga, for example, is Kurdish pronunciation, in Persian it is pronounced "Peesh-marga". The fact that they are ethnically Iranian, and different to both Arabs and Turks (although sunni like the mentioned two) has always meant they're and will be the odd one out. And, despite at times rivalry between Persians and Kurds (both Iranians), The Kurds have Always allied with Iran when fighting the Turks, and Arabs, throughout history.
