How do the following theoretical frameworks of international relation and global politics view states and other actors in the international system: realism, liberalism, Marxism and constructivism? Solution Realism suggests that states should & do look out for their own interest first.Realism persumes that states are outvfor themselves first and formost.Realism suggests that international relations is driven by competition between states and states therefore do and should try to further their own interests.Realists believe that greater power is the only way for states to secure their soverignty and this leads to the belief that states are the main players in international politics because the system discourages individuality in favor of these types of power struggles.Realists believe that power is gained through war or the threat of military action they also believe that there is no such thing as lasting alliances or peace due to this power grabbing system. Liberal theory too believes in the view that states are seeking military power to combat anarchy.For liberal theory there is hope for world peace if state seeks common ground, forming alliances and institutions for policing the world powers.Liberal unlike realists take into account the individual attributes that states possess and allow for the idea of lasting alliances based on comon beliefs and ideas and attribute more power to common institutions then to states.Liberals believe that common ideas can lead states into interdependence and so remove allies as threats to soverignty.They emphasize that the real power for states comes of mutually held ideas like religion ,language,economies and political systems that will lead states to form alliances and become interdependent. Constructivism has been described as a challenge to the dominance of neo liberal and neo realist international relation theories.Michael barnett describes constructivist international relations theories are being concerned with how ideas define international structure how this structure defines the interests and identities of states and how states and non state actors reproduce this structure.The key tenet of constructivism is the belief that international politics is shaped by persuasive ideas,collective values,culture and social identites.The failure of either realism or liberalism to predict the end of the cold war boosted the credibility of constructivist theory.Constructivism most concerns itself with the role of ideas in shaping the international system.By udeas constructivism refer to the goals, threats, fears , identities and other elements of perceived reality that influence state and other elements of perceived reality state and other elements of perceived reality that influence states and non state actors within the international system.
