Peace, after which we all long for, is mainly defined as the absence of war and violence. But we have to accept, that peace on earth looks very similar to an earth without mankind. Thus we can at least be sure that one day peace will really exist on this planet. Knowing this, all "human" beings have the duty to learn how we can find better ways to avoid violence and to tame the warmongers. And this is the point: Any kind of attempt into this direction looks like peace - even in a violent world.
