. acting, based on a medium and long term vision. The dynamics of the current security environment highlights two main challenges: the identification of constancies and foreseeing any possible internal, regional and international phenomena which might impact upon Romania's national security. 32. In foreseeing and preventing major security issues at the global level, an important part is played by the United Nations Organization both when it comes to consultations as well as to decision making related to solving some regional crisis. Disputing more frequently lately the international regime of some treaties and understandings regarding armament, deployment and stationing of troops and military capabilities, and the measures to strengthen confidence and security at regional and international level may deepen fragmentation, divisions and cleavages, generating a turbulent reconfiguration at the international relationships level. 2.2. Security Dimensions at Euroatlantic Level 33. Romania's position on the Eastern flank of the North‐Atlantic Alliance and of the European Union, as well as at the crossroads of some areas with a high security shows that defense and security surpass the area of responsibility of a single state. It is necessary to revisit some concepts and establish new measures to ensure predictability and consensus in handling national instruments both independently, as well as in allied and community context, OSCE being, in this regard, an important element within the European security system. 34. The main warranty provider when it comes to Romania's security is The North Atlantic Alliance, the transatlantic relationship representing the strategic binder which awards coherence and consistency to NATO actions. The solidity of the transatlantic relationship depends on the United States' maintaining their commitment in Europe, as well as the way allies and European partners will allot financial assistance to develop their own defense capabilities. 35. An important actor in the European and Euro Atlantic environment is the Russian Federation. Its actions in the Black Sea Region, infringing upon international law, questioning international order, preserving frozen conflicts and the annexation of Crimea have raised again the NATO awareness upon fulfilling its fundamental mission that is collective defense, as well as the validity of the security arrangements agreed upon with Russia at the end of the XXth century. 36. The European security architecture has been under constant threat by crisis and conflicts which are ongoing in the close vicinity, in the East and in the South, which might impact, directly or indirectly upon Romania's national security interests. The recent evolutions in the Eastern Neighborhood, in the Middle East and the Northern Africa generate multiple challenges to the security of the community environment, thus the need that the European Union revise and strengthen its policies in the field of security and collective defense and internal affairs becomes more obvious. 12
