I don't mean to be negative but I think the reality is no. I ponder on my dinner table. Peace is not achievable in a continuum even among family. We humans seem to be wired with an animalistic instinct to attack each other. Jesus was an amazing example of self-control and restraint that most of us humans seem unable to posses. We do not seem capable of mastering the ability to allow others to hurt us without hurting them back, and there is a lot of hurt in the world. If we all followed the commandment to love our God with all our hearts, mind, body, and soul and then our neighbor as well--perhaps it could happen, but turning the other cheek willingly is a easier said then done. Only very few people have such pure and amazing souls.
