There’s nothing American Jews love more than Israeli soldiers, except perhaps, Israeli spies. Go to American synagogues—especially Orthodox synagogues—and you’ll find boys wearing green-and-yellow skullcaps bearing the Israel Defense Force’s Hebrew acronym. A central element of the Birthright Israel program, which aims to instill a love of Israel and Judaism in young American Jews, is their mifgash, or encounter—often R-rated—with Israeli soldiers. For my Bar Mitzvah, I was given a tome celebrating the exploits of Israel’s external and internal spy agencies, the Mossad and Shin Bet. My 6-year-old son recently came back from the library of his Jewish school carrying a volume entitled Keeping Israel Safe: Serving the Israel Defense Forces.
