very quickly before I have to dash off to work.... to me the psychology of peace is about how we as individuals are in our own hearts and minds, how aware of our own dark, shadow side we are, whether we project our own aggression out on to others without realising and therefore are unable to take responsibility for it. This then spereads like a virus through the world. We only see happening in the world what is a reflection of our inner selves - unless we take responsibility for our thoughts and actions. when we point the finger and say "it's them,it's them" we might need to look at what WE are doing ourselves......
blessings and peace
