Abstract:
After the Cold War, NATO did not only disappear, but it also enlarged. Although the CSDP is on the agenda, it has not made significant progress in terms of assets and capabilities. For the study on the relationship between the two, most current studies are based on realism. Starting from the perspective of constructivism, this paper used documentary analysis to review the normative history of NATO and the history of the normative development of the CSDP, and found that the core political norms and security norms of the two are completely consistent. Finally, it concludes that the NATO norms influence the CSDP through the three levels of norm entrepreneurs, daily security practices, and the institution, so that the CSDP cannot be independent. This paper provides a new study perspective of the relationship between the two.
