Will world peace ever be possible?

World peace is possible, but in today's world, it would be difficult. If only Ghandi would come to life, then he could tell us a thing or two about non-violence! People think that violence is the answer to everything, and that's the reason for wars and murders. Hate is at the root of violence, and people hate because of differences. Come to think of it, everyone is different, and there will always be disagreements between people. It's all the psychos in this world that make world peace impossible! If we shipped out all the psychotic, violent people to another planet, then there would be peace on Earth.
