Peace is the concept of harmony and the absence of hostility. In a behavioral sense, peace is a lack of conflict and freedom from fear of violence between individuals and heterogeneous social groups. Throughout history some of the most extraordinary and benevolent leaders have used peace talks to establish a certain type of behavioral restraint that has resulted in the establishment of regional peace or economic growth through various forms of agreements or peace treaties. Such behavioral restraint has often resulted in de-escalation of rhetorical and physical conflicts, greater economic interactivity, and consequently substantial prosperity. The avoidance of war or violent hostility can be the result of thoughtful active listening and communication that enables greater genuine mutual understanding and therefore compromise. Leaders often benefit tremendously from the prestige of peace talks and treaties that can result in substantially enhanced popularity.
