In international relations, the relationship between states has primarily been analysed by observing them as having a singular identity and being utility maximizers no matter the level of cooperation. However, while realists view interests as material and objective phenomena, social constructivists tend to argue in interest flow from identity and are not first and foremost material properties (K.M. Fierke, 2015, p.83) There is a different way to analyse states and the insecurities constructed overtime, and this can be done with the theory of constructivism. Constructivism applies to how states perceive other states based on criteria of nationalism, ethnicity, race, gender, and religion. The ideology chosen by the state may form within these group of variables. This theory describes why states interact with each other, explaining when states are allies, enemies, neutral, peaceful, or aggressive towards one another. These perceptions form patterns of war and peace, giving away for the formation of foreign policy which is done by considering historical subjectivity, rather than the realist assumptions of a state is a state and all potential states could be threats. Co
nstructivism allows states to be a number of things at the same time. This leads us to understand that different states view other states through a constructed identity which fundamentally shapes perceptions of the norms made through the culture and the agents that affect the insecurities. This essay will be analysing how insecurities were constructed before the American Civil War broke out, the construction of identity in Rwanda of Tutsis and Hutus which lead to the Rwanda Genocide of 1994, and the various civil wars that took place in The Democratic Republic of Congo post-independence. These arranged group of case studies relate to civil wars which will stablish a clear base for the understanding of the construction of insecurities. In addition, it will compare the constructivist approach with different neo- realist and neo-liberal perspectives in order to broaden the standpoint relating the origins of these wars. For the international peace keeping action and global security, the essay will be focusing on the role of the United Nations and their role in peace keeping and peacebuilding at an international level has had a big impact in the relations between states.
