The norms of Public International Law and doctrine of collective security after 1945 did not stop different forms of armed interventions around the globe but especially by the US – a country which became a global champion of aggression. Armed “humanitarian” interventions are still and are going to be a reality of the present and future international relations under the umbrella of the R2P.
The ideas of “humanitarian intervention” and collective security became brutally misused by the US’ administration at the time of the New World Order. In general, World Order after the fall of the Berlin Wall in 1989 has been interpreted in various ways but the very fact is that a bipolar world order after 1945 became replaced by a unipolar world order, based on the USA as a hyperpower state.
While the political objective of the Operation Allied Force was in principle achieved, the humanitarian dimension brought quite opposite results.
