Politics is an inescapable part of human existence and social interaction invariably involves political relationships. Politics is also extremely important to the creation of a just and humane life. The area that is subject to politics covers a vast terrain and not only includes any aspect of contemporary society that directly or indirectly affects the state, but also those aspects of life that have public significance.
Politics is not limited to the state but extends beyond national boundaries into adjacent regions and the world. In a globalising world these international political relations are not limited to interstate or government interactions and membership of international organisations, but include links with and the activities of non-state actors.
Furthermore, they include political and military matters, as well as non-political affairs with political implications. The area subject to international studies thus covers a vast terrain involving peace, security, development and justice.
