A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death. Sometimes the conflict partners are so emotionally wounded or ideologically hidebound that nothing can stop the violence. But large numbers of conflicts can be resolved without killing or wounding the other side, provided the strategies for peacemaking are known. They all claim to want peace. Gandhi routinely said, don't bring your opponents to their knees, bring them to their senses.
Nonviolence means prevention before the crisis.
Serious thinking will.
