From the earliest days of Jewish settlement in Palestine, the Zionists used undercover agents in their escalating conflicts with the Arabs. From amateurish beginnings, the secret services evolved into the now vital branches of the Israeli state: Aman - military intelligence, the Shin Bet - counter espionage, and Mossad - espionage and special operations abroad. This book is a history of Israel's intelligence services covering events from the 1950s to the Gulf War. The book describes the evolution of military intelligence using previously undisclosed documents.
