What are the motifs in By the Rivers of Babylon by Nelson DeMille?

Loss of innocence is a recurring idea in the story. The members of the delegation are forced to give up their dreams of peace in the Middle East when they are hijacked by a group of terrorists led by Ahmed Rish. The members of the delegation that believe heart and soul in the mission for peace are forced to fight, the one thing that they are so dead set against. Though no member of the group is a true innocent, they truly believe that they are going to accomplish their goal of finally creating peace in the Middle East, a truth they are forced to abandon when they are hijacked.
