I think this is a very noble goal but it will be very difficult with the current structure of governments and societies. The days of "declaring war" are over. Wars from here on out will be cold wars, proxy wars, and economic wars. Atrocities will be committed in the shadows and hidden or obfuscated from the world. Violence is how the ruthless maintain power, so until the human tendency to monopolize on weakness and exploit the vulnerable disappears, war will not either. What we need are strong leaders who show alternative ways to conflict resolution to provide role models for the rest of the world to follow.
