The nationalism, that the French, in the wake of their victories under Napoleon, carried deep into eastern Europe, awoke a popular awareness of the political power implicit in large numbers of people living together within a state. The basic result of nationalism is that each state has increasingly become the centre of its own universe and is itself more and more its own first concern and pre-occupation. The consequence of separate universe of discourse is that, international morality becomes an extension of national morality. The framework considers four variables of the domestic environment for analysis. They are: socio-political-economic value system, nature of human resource, idiosyncrasies of leaders and interest and pressure groups. The framework constitutes five basic determinants of a given nation’s international relational patterns: international systemic environment; domestic environment; total national capability; national objectives; and nation’s strategies. Each of these determinants has a number of constituent influential factors in constant interaction.
