The ‘debate’ section of the Review aims at contributing to the reflection on current ethical, legal, or practical controversies around humanitarian issues.

In this issue of the Review, we invited two experts in international humanitarian law (IHL) and multinational peace operations – Professor Eric David and Professor Ola Engdahl – to debate on the way in which the involvement of a multinational force may affect the classification of a situation. This question is particularly relevant to establishing whether the situation amounts to an armed conflict or not and, if so, whether the conflict is international or non-international in nature. This in turn will determine the rights and obligations of each party, especially in a context in which multinational forces are increasingly likely to participate in the hostilities.
