A special place among the documents on national security policy takes a national security strategy (state security). It is a concept implemented in a state ensuring its security, containing in particular identification of national interests and strategic objectives, assessment of the future shaping of the strategic security environment, and rules and ways of achieving the strategic objectives in the predicted conditions (realisation of operational tasks), as well as preparations (maintenance and transformation) of the national security system (realisation of preparative tasks). The National Security Strategy is the most important document on the security and defence of the Republic of Poland. It is adopted by the government and approved by the president. The strategy is the basis for the development of more detailed documents such as the political and strategic defence directive. This paper presents the goals of the latest version of the Security Strategy of the Republic of Poland. The new National Security Strategy of the Republic of Poland documents the most serious change in the national security policy so far, involving the acknowledgement by the highest authorities of the country and saving in a strategic document that, for the first time since independence in 1989, we may be threatened with war.
