Vliv rusko-ukrajinského konfliktu na vývoj bezpečnostní a obranné strategie Evropské unie

The bachelor's thesis deals with the analysis of the impact of the Russo-Ukrainian conflict on the security and defense strategy of the European Union. The conflict between Russia and Ukraine, which escalated in 2014 with the annexation of Crimea and in 2022 with the war in Ukraine, brought new challenges and threats to the security and defense of the EU. In recent years, the transformation of the EU's security and defense strategy has become a crucial and often-discussed topic in international relations. The conflict could have a significant impact on the international system. The topic is very current and essential for the further development of the EU's security and defense strategy. The aim of this thesis is to determine how the conflict has affected the security situation of the EU and how the EU's security and defense strategy has changed from 2014 to the present. The normative and institutional basis of the security and defense strategy provides a suitable foundation for the use of a constructivist theoretical framework. The method of this thesis is based on the connection between change management theory and constructivism. The analysis focuses on three main phases of emergent change: creating a sense of urgency, creating a vision and strategy, and achieving short-term goals. It was found that the conflict has a complex impact on the EU in all areas of security and thus meets the condition of urgency. The impact of the Russo-Ukrainian conflict on the perception of security threats had an escalating character. The EU responded to the change in the security situation by developing its security and defense strategy and issuing important strategic documents. Cooperation with NATO remains crucial for ensuring the security of the EU, and EU strategic autonomy is still distant. The war in Ukraine is ongoing, and Russia's future intentions are not clear. Therefore, it is crucial for the EU's security and defense strategy to be sufficiently effective and capable of rapid response.
