I haven't seen it, but I've been very wary of such predictions: Spielberg has been so heavily involved in World War II and Holocaust projects that I find it difficult to believe that he's going to suddenly head in the other direction. As for his remarks about the cycle of violence, etc., etc., I've wondered if he isn't trying to insulate himself from the left.
Now Todd McCarthy--the best straight-on film critic in America (Lane is an entirely different sort of animal; he's in his own class)--gives his verdict. He doesn't like the Munich much but has this to say about it:
Spielberg, Kushner and Roth go out of their way to try not to demonize Palestinians or anyone else, but the story is indisputably told with Jewish and Israeli concerns at heart.
