Objectives:
The purpose of the article is to present the place of resilience in the security strategy of the North Atlantic Alliance and the Republic of Poland. This is particularly important in the context of the Russian Federation's military aggression against Ukraine and Moscow's attempts to destabilize other regions. In light of such a stated goal, the following research problem was established: will the concept of resilience to threats become a key concept for NATO and Polish security policy in the third decade of the 21st century?

Methods:
The research methods used in the research process primarily included analysis of source materials (legal acts), scientific studies and publications of government institutions.

Results:
The results of the study confirmed the thesis that the concept of resilience now occupies a very important place in the security policy of the North Atlantic Alliance and Poland. This is their response primarily to the aggressive policies of the Russian Federation: the attack against Ukraine, threats against NATO (including Poland), the attempt to destabilize the situation in other regions of the world. NATO, including Poland, has realized the need to build efficient collective defense mechanisms and resilience to military and non-military threats.

Conclusions:
Conclusions of the research indicate that the North Atlantic Alliance is increasing its emphasis on creating resilience to threats. Unfortunately, in Poland, the apt provisions of the National Security Strategy regarding resilience and universal defense have so far remained only in the realm of declarations.
