War is a conflict between political formations (states, tribes, and political groups, etc.), which happens in the form of battles between armed forces. The main means of achieving the goals of the war is an organized armed struggle as the main and decisive means, as well as economic, diplomatic, ideological, informational and other means of struggle. In this sense, war is an organized armed violence, which purpose is to achieve political goals.
Wars are an integral part of human life. Development of wars is the result of technological and demographic changes. It is a process in which long periods of strategic and technical stability are replaced with sudden changes. Features of war change in accordance with the development of means and methods of warfare, as well as changes in the balance of power in the international arena.
War is a constant companion of the human history. Up to 95% of all known societies have resorted to it to resolve external or internal conflicts. Scientists estimate that over the last fifty-six centuries, there have been about 14,500 wars, which killed more than 3.5 billion people.
The main cause of wars is the desire of political forces to use armed struggle to achieve a variety of foreign and domestic purposes. With the rise of mass armies in the 19th century, xenophobia became the important tool for mobilization for war. On the base of xenophobia, ethnic, religious or social hatred can be easily incited, and therefore from the second half of the 20th century, xenophobia is the main tool of incitement to war, aggression areas, certain manipulation of the masses within a state, etc.
If the first half of the 20th century was a period of struggle for world domination, now causes of war are represented with contradictory trends of universal growth and fragmentation of the world. Clashes in Angola, Korea and Vietnam, which took place after the Second World War, were nothing more than a manifestation of the confrontation between the superpowers USA and the USSR, which, being the owners of nuclear weapons, could not afford to enter into an open armed struggle. Another characteristic of wars and military conflicts in the 1960s was the national self-determination of the people in Asia, Africa and Latin America. National liberation wars were often wars of puppets, in which one or the other superpower tried to use local militias to strengthen and expand its sphere of influence. In the 1990s, there have been new causes of armed conflicts: inter-ethnic relations, weakness of the state, competition for control over natural resources. Thus, along with disputes over the state, an essential cause of wars is affirmed disputes within states. In addition, there have been religious causes of armed conflicts.
There is also a moral criterion – just and unjust wars. Just war is a war waged for the sake of protecting order and the rights and, ultimately, reaching peace. Its mandatory condition is a just cause; it should start only when all peaceful means have been used.
