International security consists of the measures taken by nations and international organizations, such as the United Nations, to ensure mutual survival and safety. These measures include military action and diplomatic agreements such as treaties and conventions. International and national securities are invariably linked. Since the end of the Cold War the definition of international security has expanded to include more issues and actors. Post-World War II definitions, assumptions, and security institutions, they assert, are no longer sufficient to deal with the modern world’s most pressing security problems. They argue that in order to face the problems of the twenty-first century, we need a more comprehensive definition of security with the extended constituency and a new kind of integrated strategic thinking —one that encompasses the increasing number of threats to an increasing number of actors. As indicated, "security" as a concept and as a phenomenon at the end of the cold war has taken on new forms. There are new security agendas, new security manifestations, and new rules of the game for security policy. How to explain and comprehend security as part of international relations in the so-called new world order? In a way we have three different realms for the term "security." First, the broad, day-to- day use of the word, referring to a position aspired to: of being safe, secure, protected. Second, the political use of the word, referring to political actions, processes, or structures that can secure the safety of a political unit. In the political sphere the term "security" is used as a political tool, for example, to provide a certain phenomenon with a specific priority by placing it in the realm of high politics. Finally, "security" can be used as an analytical concept to identify, describe, understand, explain, or even predict phenomena in the general social realm; phenomena such as "security policy," "security- policy interaction," or "security institutions and structures." A significant change in the political use of the term "security" was, however, the invention of the concept of security policy. The United States, as the most important unit in the international system, was the initiator. In 1947 the US administration introduced the National Security Council, which became a model for several countries around the world. This also involved the introduction of a new concept, "security policy." Now it became possible for states, in linguistic terms, to conduct or pursue a security policy. Security policy was more than defense policy, more than military policy, more than a policy aimed at being prepared for war. Security policy also aimed at avoiding war. Security policy encompassed internal, domestic security, economic- development policy, and policy for influencing the international system so as to create a peaceful environment, regionally as well as globally, including foreign aid to developing countries.
