The nature of the media plays a key role in shaping general opinion, making them a major tool of politics. From its beginnings, the media have been used for political or war purposes, and they reached their peak during the World Wars. With the development of new media, advanced and more subtle possibilities of influence were conceived - propaganda content outgrew its basic concept of transmitting messages and became a literal way of warfare. Entertainment media are involved in the process of psychological neutralization of the notion of terrorism and war, which in the most extreme examples can lead to arbitrary involvement in war without real knowledge of the possible consequences. New media have become one of the main tools of terrorist groups with the aim of war mobilization, using specific cognitive techniques with careful segmentation and targeting of a specific audience. This paper will deal with the development of the use of the media for military purposes, the strategy of creating such content and the development of terrorism through new media. In addition to acquiring a new form of military force, the development of the media enabled a completely new form of cold warfare and created a long-term impact on the social aspect of human perception of violence, ie neutralization of terrorism and war and real motives and reasons behind them.
