Under the traditional security paradigm humanitarian intervention is contentious. As discussed above, the traditional security paradigm places emphasis on the notion of states. Hence, the principles of state sovereignty and non-intervention that are paramount in the traditional security paradigm make it difficult to justify the intervention of other states in internal disputes. Through the development of clear principles based on the human security concept, there has been a step forward in the development of clear rules of when humanitarian intervention can occur and the obligations of states that intervene in the internal disputes of a state.
