Elliott Jaques explores what is evil about terrorism and the specific good that this evil destroys. It is essential to formulate the foundations of systems of relationships, justice, and law that can guarantee the global victory of good over evil. The basic glue that allows humanity to live together is global mutual trust that each will not harm the other. To be able to rely upon that bond is the final good. For individuals to decide to break that bond is the essence of evil. One prominent condition that succors and supports the primal evil expressed in terrorism is the experience of circumstances in which some seem to be succeeding unjustly at the expense of others. The war against terrorism requires both that the USA leads a coalition of willing nations against the perpetrators of evil as well as becoming the leader of the people of the world in sustaining the primal good of world-wide mutual trust.
