Security as a concept is quite difficult and complex to make sense of as often various definitions of security in scholarship, if not used precisely may make different meanings to all people or even no meaning at all. This paper uses security as a concept, drawing from pertinent schools of thought to derive an understanding of what security means following certain actions or choices that states pursue regarding their own security. Using Uganda’s military intervention in the Democratic Republic of Congo and in Southern Sudan in 1996 and 2013 respectively to clarify the meaning of security is the cornerstone under which this piece of work is hinged.
