Today, peace means the ascent from simple coexistence to cooperation and common creativity among countries and nations.
Peace is movement towards globality and universality of civilization. Never before has the idea that peace is indivisible been so true as it is now.
Peace is not unity in similarity but unity in diversity, in the comparison and conciliation of differences.
And, ideally, peace means the absence of violence. It is an ethical value.
