A couple of quick thoughts:

• People in the midst of a conflict usually speak about achieving peace, as if it were a destination, like going from point A to point B. But I understood some time ago that this is not the case. Peace is a state of equilibrium that, once reached, is always in danger of slipping. It is probably an equally difficult job to maintain peace as to reach it from a state of war, so that future wars, whose seeds are already germinating, seem almost inevitable.
• Young people do not have the privilege (or the misfortune) of remembering the horrors caused by previous conflict, so every new generation has been eager to start the ball rolling again. Therefore the importance of education.
