Wybrane uwarunkowania bezpieczeństwa narodowego i międzynarodowego na progu XXI wieku. Cz. 2

Selected processes and changes that occur in the contemporary world have been discussed and there have been presented opinions of scholars that deal with explaining the mechanisms of the world functioning and development. Some selected processes that shape the modern world (called mega-trends or trends) such as globalization, demographic explosion, migrations have been characterised. Selected mega trends have been described taking into consideration possible threats that may appear for national and international security. A particular attention has been drawn to the identification of new threats that have not appeared before or that have not been considered due to their small probability. Then the implications for Poland’s defence have been presented, in particular for developments in commanding the defence resulting from the emergence of new threats, often of diversified character. The author tried to point out, in connection with changes taking place in the modern world, to the need of introducing certain changes to improve the defence commanding subsystem, mainly in order to make it more flexible and effective in new and changeable conditions.
