  Victims can (and very often do) simply move away from the scene of the trauma rather than seek revenge or engage in forgiveness. In recent years there has been a quiet exodus of approximately 100,000 Palestinians from the West Bank and Gaza, to Europe and North America. Most Holocaust survivors, uninterested in revenge or forgiveness, simply moved thousands of miles away from the sites of their horrific memories and swore never to set foot in the countries that had persecuted them. Others replace revenge with commemoration, dedicating themselves to the creation and maintenance of monuments and museums. Thus, for example, many of those handing out the ID cards at the Holocaust Museum in Washington D.C. are holocaust survivors, as are many of the guides in Jerusalem's Yad Vashem memorial.
