Good, healthy democratic societies are built on three pillars: there's peace and stability, economic development, and respect for rule of law and human rights. But often, we take stability - peace in terms of security and economic activity - to mean a country is doing well. We forget the third and important pillar of rule of law and respect for human rights, because no country can long remain prosperous without that third pillar.

It may seem sometimes as if a culture of peace does not stand a chance against the culture of war, the culture of violence and the cultures of impunity and intolerance.

It may be a painfully slow process, and fragile and imperfect when it is achieved. But peace is in our hands. We can do it.
