The truth behind Munich...
I haven't seen Speilberg's Munich yet...but here is a good look at the fiction in the movie.
In Munich, a hastily assembled covert assassination team is gathered by Golda Meir and given a list of targets—the men responsible for the attack. There are 11 Palestinians (a convenient match to the 11 dead Israeli athletes) who must pay the price. It didn't happen that way. Israel did authorize and empower a counter-terror assassination campaign in Munich's wake (more on that below), but no list of targets was ever given to an assassination team. Indeed, there was no "one team" charged with carrying out any sort of ongoing revenge operation. Specific targets were identified and then approved for assassination by top Mossad officials, and ultimately by the prime minister, as evidence grew in Israeli eyes that these individuals were likely to plan further attacks. Palestinian operatives, including many who had nothing to do with the Munich Massacre, were sentenced to death on a case-by-case basis. The list of targets was constantly changing. Assassination teams were sent out, mission by mission, as evidence and opportunity warranted.As Klein says in his article,
Revenge was the atmosphere—but preventing future attacks by networks that Israel saw as threatening its citizens was the goal.
