• Romeo Dacian BUHAI The 4th Infantry Division Headquarters


The changes that took place at the end of the 20th century in the international relations system led to changes at the global level, but especially at the regional level, in terms of the prospect of understanding how security was achieved. In this respect, the continued struggle of actors to reconfigure power centers, the increased development of existing threats and the emergence of new ones, have led to the reshaping of the regional and global security environment. Thus, in this article we aim to capture some of the realities that govern the European security environment at the beginning of the 21st century.
