The sole reason of the state has the support of the assumption that no central authority reigns above the state. Only powerful and satisfied states can run their affairs in such assumptions, which prove realism as a reserve for the satisfied and powerful states.
The realist worldview has such basic principles as that world politics is a struggle among self-interested states with each pursuing its self-interests (Kegley and Blanton 32). In addition, international relations involve nations’ pursuit of power to secure their interests. Thus, international relations rest on the competitive pursuit for power by states to secure their interests.
The realist worldview has the advantage of enhancing state sovereignty as each state controls its power and control. On the contrary, it makes the world more susceptible to warfare and violence as each state works towards securing its interests. Additionally, it leads to unfair competition between states, which culminate into rivalry, struggle for power, and poor international relations (Kegley and Blanton 33). As each Middle East state struggles to achieve power and control of the region, conflicts erupt, leading to poor international relations, for instance, the strained relations between Iran and Iraq.
The liberal worldview focuses on the use of ethics and reason, especially through the empowerment of international laws and institutions, as a means of achieving a cooperative and orderly world, with working international relations (Brink 98). As a result, states will only have good relations with other states whose characters are in line. For instance, peaceful states will gain the support and thus, form relationships with other peaceful states. As a result, if a state has peace, it will be able to attract peace, and thus, better foreign affairs with others.
