Studien behandlar de motiv den amerikanske presidenten Ronald Reagan fann till att USA skulle intervenera på Grenada, samt hur denna motivbild skapades. Som teori användes John J Mearsheimers offensiva realism och metoden tog sin utgångspunkt i Ernesto Laclau och Chantal Mouffes diskursanalys. Materialet som undersöktes bestod av texter och uttalanden med Reagan som avsändare. I analysen visade sig både motiv tillhörande den realistiska och liberala diskursen. Den liberala diskursen var dock underställd den realistiska, vilket visade på en hegemoni för den senare.

The aim of this thesis is to examine to what extent China acts as a superpower in the South China Sea. In order to accomplish the purpose of the study the International relations theory Offensive realism has been applied. The thesis is a case study, with the premiss to test Offensive realism on the selected case. Data is gathered from books and articles. Within the framework of Offensive realism, three categories have been selected to study China’s actions on three different occasions. The categories that have been applied are diplomacy, economy, and military. The occasions occur at different time periods, 1974, 2012, and 2014, in order to be able to give the study a wide basis.   The result shows, that from an Offensive realism perspective, China acts like a superpower in the South China Sea. In the cases studied China acts as a superpower in all of them. Breaking it down to the applied categories, diplomacy, economy, and military, it is showcased that China’s actions in the region are corresponding to that of a superpower eight of nine times. China seeks control of the region's wealth to strengthen its own economy, which in turn strengthens the country's military. Furthermore, the growth of the economy and resources means that control of the area is centered to China. Which increases the chance for China of creating a hegemony in the region.

BRICS is an organisation consisting of the developing countries Brazil, Russia, India, China and South Africa. Since its creation it has quickly become a great force of power on the global arena and is expected to encompass 42% of the world’s population after the upcoming membership expansion. This sparks interest in the study of the development of the organisation. Based on the research question “How can the development of BRICS be interpreted based on the theory of offensive realism?” the study explores the field of research using a qualitative case study with theory consuming design. The paper presents the result that the member states use the organisation to ensure the safety of their respective countries. This is being conducted through the increased cooperation among like-minded developing countries and through the establishment of their own institutions. These measures are implemented with the intention of balancing the west and increasing their own power.
