The article covers the notion of star wars, aiming to show that it is an idea describing the reality, not just a story (although often associated with one). The space policies implemented at present by different countries prove that space conflicts are still possible. Therefore, the security of the space activity pursued by various countries is compromised - not only in space but also on Earth. And although only some countries carry out space activity, the effects of this activity (be it civil or military) are felt by the entire international community. The militarisation of space is slowly entering a new stage: the stage of use of active satellites, designed to destroy pre- defined targets. This situation means that star wars are not fiction since it can happen in the future that feuding countries will be settling the conflicts arising between them in cosmic space.
