With the end of the bi-polar world at the beginning of the 1990s a change of the security threats occurred. From the 1940s until the end of the 1980s the biggest threat was the danger of a worldwide conflict between the states of the East and the West.
After the collapse of the bi-polar world in the 1990s the urgency and the timelines of the security threats changed. Terrorism, the spread of weapons of mass destruction, and civil/domestic and regional conflicts can be considered among the most urgent threats.
This paper concentrates on the analysis of armed conflicts that had an influence on international security in the last thirty years. The development in this period from the reduction of the international tension in the 1990s to the increase of tension over the last ten years is also analyzed.
