Peace as the end of the Republic

Resumen

It is evident that the international order has been changed at the beginning of the twenty-first century after the terrorist attacks of September 2001. Peace is the essential end of every constitutional democracy, internally –in the relationships that its members maintain among themselves-, as well as externally –those relations that a society sustains with others. The problem arises especially in the relation of constitutional democracies with other political regimes. Whereas Kant defended that the best means to achieve peace was the expansion of the republican regime, Rawls' defense of liberal democracy did not envisage its expansion. The relations of a constitutional democracy with other societies, whether democratic or not, necessarily require a limitation of sovereignty in their exercise abroad. However, the relations among different sovereigns remain underdeveloped, practically at the mercy of the good or bad will of each of them, without a praetor with the capacity to establish the universal will that should prevail in the relations among states.
