National Security and War
National security is a very important concept in international politics. National security means the guarantee of territorial integrity and sovereignty of a state. The government must counter any external pressure on its sovereignty. State must be free from any kinds of psychological anxiety. In the history of international relations many governments have launched wars of aggression or were designed military interventions abroad and have claimed that their policies to defend or preserve national security. This was a rational for both the American intervention in Iraq in 1990 and in Afghanistan in 2001 . Alll states maintain military forces, so that the state could deal with any futures. The threats could come in the form of crimes, rebellions, secessions, revolutions, or even war
Thus, in the name of national security wars have frequently taken place in the history of world politics. Sometimes, it has taken the form of civil wars, limited wars, and conventional wars or even international wars, total wars or nuclear wars. This has raised the question of a true definition of war. Quincy Wright says, Any armed conflict between two or more nation stats is war. Charles Hodges point out that the use of organized armed forces against a state for achieving its end is war. In brief, war is a struggle among political units, within and between states involving organized fighting forces, and resulting in a sizable number of war-related casualties.
War could for a number of reasons. History demonstrates a set of causes of war. A review of literature on the causes of war reveals at least seven primary factors or conditions responsible for the outbreak of war. They are human aggression, elite and popular fatalism regarding war, small group conspiracy, economic imperialism, nationalist expansionism and irredentism, systemic inadequacy, and the general cycles of history.
