That was my thought when I read the article. I believe their culture encourages serving in the military of their host country and they serve in the IDF, nachon?
I think you are thinking of Druze.
Plenty of Bedouins do serve in the IDF, but it’s voluntary and more a way to assimilate into society. I don’t think they are subject to the draft. ( I could be mistaken; there was a change recently and I believe Nazarene Arabs are subject to the draft now.)
