The approval of the new security strategy of the Republic of Poland in May 2020 required paying attention to the terminological aspects of the concepts used in this document, as well as to legal issues, which were mainly connected with the problem of whether this act should be formally countersigned or not. An equally important issue was to draw attention to the fact that, in practice, two strategies were being developed in Poland’s legal system—one approved by the President of the Republic of Poland in his decision of May 12, 2020, and the other, which was in the form of a resolution of the Council of Ministers, applicable from 9 April 2013. The current strategy was preceded by earlier strategies and the White Paper on National Security of the Republic of Poland. The strategy of May 12, 2020 is a comprehensive document that sheds light on all elements of national security. Its content addresses such phenomena as hybridity, operation in cyberspace, the need for new technologies, and artificial intelligence.
