Peace is possible and not to be feared. Enemies can renounce bitter opposition and reconcile to genuine peace. In my own life, today, I sat and spoke with one with whom I had real differences. We never apologized for our social/political tensions of the past. Somehow, after several months, we simply decided to just talk for hours in complete acceptance of each other. In the same way peace, like war, can be a choice. We may not always make the choice when we should, but eventually, peace can happen when the parties involved are willing.
See peace in action in the political sphere: Observe Pearl Harbor 2016, a modern example of reconciliation.
