Romania’s membership of NATO and the European Union has many advantages, but also risks for each of them. Romania continues to strengthen its position and role within NATO and the EU. Romania has shown that it is a loyal and credible partner in its relationship with all international organizations. Romania’s strategic documents with NATO and the EU are well structured and clear. These include mission, vision, strategic objectives and ways of cooperating with each other, as well as the financial, material, human and informational resources needed to implement them. The objective of our research was to identify the main threats, risks and vulnerabilities of Romania as a NATO member state. The analysis has led to the discovery of new ways of reducing risks and threats, as well as solving the major vulnerabilities of Romania. The research is based on the National Defense Strategy, the Romanian Armed Forces Endowment Plan for the period 2019-2028 and other strategic documents underpinning the development of the cooperation between Romania and NATO. Within the analysis process the main threats, risks and vulnerabilities of Romania in relation to NATO were identified. Based on the analysis carried out, several ways of action are proposed through which Romania can strengthen its defense and security capabilities. The results of the research are relevant both theoretically and practically because they show the major changes that Romania has made after entering NATO and the exceptional performances achieved both in the development of the defense and security capability and in fulfilling the commitments assumed by Romania with NATO and other organizations it belongs to.
