World peace is an ideal of freedom, peace, and happiness among and within all nations and/or peoples. World peace is a Utopian idea of planetary non-violence by which nations willingly cooperate, either voluntarily or by virtue of a system of governance which prevents warfare. Although the term is sometimes used to refer to a cessation of all hostility among all individuals, world peace more commonly refers to a permanent end to global and regional wars with future conflicts resolved through nonviolent means.
