Strength, Peace and Security are the pillars of International Relations

In today's transnational world, a sustainable national security policy cannot be achieved through national capabilities alone. Sustainable national security instead rests on three pillars:

1. A multi-sum security principle based on justice at all levels, multilateralism and multidimensionality (including human, environmental, national, transnational and trans cultural/transcivilizational security);

2. Symbiotic realism in international relations, whereby mutual cooperation among states results in non-conflictual absolute gains that is peace.

3. Transcivilizational synergy which results from mutual respect, multiculturalism, cosmopolitanism and cross-fertilization, and will lead to global justice, security and prosperity. This is essential reading for anyone interested in an innovative approach to the complex yet central subject of sustainable strength.
