Compared to the best crime and spy novels, it lacks depth and humour. I mean the good guys are really really good, most of them are into Mossad only because some of their relatives were killed by the bad guys that are really really bad. I mean the worst thing the good good guys do in the novel is smoking cigarettes, despite they promised to quit to their wifes. Obvioulsy the bad bad guys smoke because they enjoy to smoke, the good guys smoke because they have to, everybody knows that keeping the world safe from the bad guys is a stressfull job.
Plus there is a rankin for good and bad guys: the very very good guys are in the Mossad, the very good guys are in the CIA, the good guys are in MI5, the guys are in the French Secret Service, the bad guys are in the new KGB, FSB, the very bad guys are former KGB agent, the very bad bad bad guys are in Al-Qaeda.
Compared to this novel, Spielberg's "Munich" looks like a movie wrote by Hamas.
