What is the theme in 2002 Arab and Jew: Wounded Spirits in a Promised Land by David K. Shipler?

In the end, the only theme of Arab and Jew is victimization. Two proud, passionate people are victims of history, thrust together into competition over a single strip of sacred land. Old timers on both sides of the conflict are victimized by the loss of a peaceful coexistence they remember from their childhood. The youngest generation on both sides is victimized by the legacy of hateful bigotry being embedded into their heads and hearts by their parents' generation. They will have to strive mightily to overcome these if they in old age will hope for peace.
