This chapter has surveyed the main approaches in IR theory, each of which possesses a legitimate, yet different, view of the world. It is important to note that the theories listed in this chapter are not exhaustive and there are many more that could be examined. However, this is a good starting point for achieving an overall understanding of the field and where the most common approaches are situated. Hopefully this has helped you consider your own theoretical inclination – or at least piqued your interest in determining where you might stand. It is not necessary to adopt one theory as your own. But it is important to understand the various theories as tools of analysis that you can apply in your studies. Using a theory to critique an issue, as this chapter did with the United Nations, is to understand the reason why these theories exist. Simply, they offer a means by which to attempt to understand a complex world. As international relations has grown in complexity, the family of theories that IR offers has grown in number. Due to its complexity and diversity, it is common for newcomers to have some difficulty in grasping IR theory, but this chapter should give you the confidence to get started.
