After the collapse of the Soviet Union and  the so-called “Eastern bloc”, hopes rose for the creation of such an international system that would allow for a significant reduction in the military factor in relations among the countries, and would significantly reduce the intensity of political or economic conflict. A series of agreements on arms reduction and control was signed, and there were attempts to realize the provisions concerning the renunciation of the use of force among the states. There were also efforts to limit the rivalry of the great powers in the strategically and economically important areas of the world. The idea of “a world without wars” or major conflicts very quickly proved to be a pipe dream. Political and military conflicts – as well as increasingly economic ones – of different basis and different intensity continue to occur in all parts of the world while the international community often remains helpless in solving them. The threat of terrorist and cyber terrorist activities is also growing, and recently the issue of refugees has become an important one in the contemporary politics of many countries.

An increasingly important question is not only the nature of armed conflicts but also the way in which they are reported in the media. The question is whether the media are  a neutral observer and impartially report the war or deliberately distort the message to fuel the excitement in the international community.

At the beginning of the twenty-first century, more and more dynamically changing international situation has impact on redefining security strategies of individual countries or political and military blocks. Challenges and threats which the world is facing in the twenty-first century affect our perception of national and international security.
