Abstract: Reconciliation of past events is beneficial for resolution of conflict but not essential to resolve geographic, political and economic conflicts that can cease violence. Past events are immutable in spacetime and interpretation of past events may be different for different observers. These events that differ among observers may lead to very different outcomes associated with the event because the activity of the brain is chaotic. Although humans have an innate desire to reconcile past events, resolution of conflicts should be initially concerned with the present and future. Reconciliation is a long and arduous process. In this invention electromagnetic waves that are coherent with natural waves generated by the brain of those in conflict are broadcast through air or wire into areas of conflict to aid reconciliation. Peace may be more easily obtainable with this invention, but this invention will not in itself solve the problem of reconciliation.
