When Israel was still a dream, an idea far from plausible reality, Jews from the Arab world risked their lives for the nascent state and went undercover in enemy territory: Syria, Egypt, Lebanon, and Jordan. This special Palmach unit, dubbed the “Arab Section” or the “Ones Who Become Like Arabs,” received cursory training in spycraft, intelligence gathering, and sabotage. Resources — cars, cameras and radios — were in short supply, as was money to cover ordinary expenses and even salaries. Yet, the Arab Section infiltrated Arab communities, gathering useful intelligence and radio reports, carrying out acts of sabotage and even attempting an assassination.
The exploits of this elite unit of the Haganah, the Jewish underground army in Palestine, are told through the lives of four of its Arab-Jewish recruits in Spies of No Country: Secret Lives at the Birth of Israel (Algonquin Books of Chapel Hill, 2019). Author Matti Friedman uses material from interviews, Israeli military archives, unclassified Haganah documents, published histories and unpublished testimonies from participants to tell the story of four of the men who helped establish what would become Israel’s intelligence services.
These young men, Jews born in Middle Eastern communities, could easily navigate between two worlds, but were, for the most part, amateur spies who survived mainly by their wits. They paid close attention to Arab morale, their opponents’ military strength and schemes, any potential subterfuge plans, and most importantly, what was happening around them.
