Sustainable nationhood' requires not only international security but also internal security.
Most countries are strong in some aspects of internal security but weak in others.
Germany for instance deserves kudos for its leadership in ecological security, but lower marks for human security with the resurgence of violence directed at ethnic minorities. The ecological security of Pakistan and Costa Rica could still be undermined by social and ethnic strife. And the strides in cultural tolerance made in Canada might still be sidelined by an addiction to over-consumption of energy and material goods. But sustainable nations also require secure borders. Some countries are promoting common security regionally as well as at home.
