We need a brief assessment of the international security environment in order to have a more realistic picture of the world we live in, having the perspective of threats, risks and vulnerabilities. The current and future security environment is characterized, among other things, by its complexity of actors, dynamism of threats as a result of the rethinking of the political-military postures of some states with military potential ore emerging states and non-state actors. In the foreseeable future, the security environment will continue to be influenced by multiple challenges, risks and threats, caused by the globalization phenomenon and political, economic, military and technological interdependencies which can provoke strategic surprises. The European area is in a continuous process of transformation with strategic implications. The systemic transformation will affect the European states and their adjacent regions visibly but distinctly, but the impact on European and Romanian security will be differentiated in the long run.
