28. International law and the use of force - the jus ad bellum


Learning outcome

After completing this activity, the student should be familiar with the means and methods of warfare (ius in bello and ius ad bellum) in contemporary international environment.


Watch the lecture of Naval War College, the Department of the Navy, the Department of Defense and try to identify contemporary ways of use of force and its justifications in contemporary international law, especially in relation to humanitarian crises and protection of human rights of individuals


A traditional way to characterise the norms that govern the laws of war is that between ‘ius ad bellum’ (the right to engage in war) and ‘ius in bello’ (the law of armed conflict, i.e., the right which applies in a state of war). This understanding seems to simply refer to the rules that determine the circumstances under which one is absolved of any fault for belligerence, and those that stipulate how one should act once a state of war is a reality. Serious problems emerge, however, once the status of these rules is critically examined, especially in the field. It is always connected with the new types of battlefield and certain conditions in the armed conflict.
