One of those calculatedly commercial boom-doom novels by a journalist seen or heard on the frequencies. The Masada Plan is Israel's potential nuclear riposte to the rest of the world, particularly the US. The Masada was that historic plateau fortress where 960 Jews held off 15,000 Romans; in roughly the same ratio, three million in 1979 are resisting fifty million Arabs. Dom Shalzar, Israeli ambassador to the UN and a fine figure of a man, reveals the plan's existence to his mistress, a fine figure of a woman, who's sure to reach the US Secretary of State, via just the right WASP in the ointment. Finally she is asked to spy for her country and she does so guiltily and well. It's all typecast stuff with some yucksome sex, and hasn't Kissinger enough on his mind without thinking about a successor who refers to ""the goddamn Jews.
