Self-Determination, Terrorism, and the International Humanitarian Law of Armed Conflict

A preliminary definition of international terrorism was agreed by the world community in 1937. Since then, a World War and the Cold War have made any such modern consensus impossible. In particular, the UN principles of equal rights and self-determination of Peoples' have caused political and juridical confusion, in that liberation fighters who utilize terror methods as one tactic in an overall political strategy to achieve self-determination are frequently termed terrorists', and are prosecuted as such.
In order to regulate wars of self-determination under international law, and to control the means and methods of warfare utilized in them, international humanitarian law (IHL) was extended in 1977 to include armed conflicts for the right to self-determination as enshrined in ... the Declaration on Principles of International Law concerning Friendly Relations and Co-operation among States in accordance with the Charter of the United Nations'. Thus, acts of terrorism perpetrated during armed struggles for self-determination are separable from random acts of international violence and, when perpetrated by states or insurgent forces during wars of self-determination, may be prosecuted under IHL as war crimes.
However, although states are obliged to seek out and prosecute the perpetrators of illicit acts of warfare, they rarely do so. Dr Chadwick argues that, should IHL be fully utilized during wars of self-determination, if only for purposes of guidance, the separability of illicit acts of war would enable the international community to reach consensus more easily in regard to a definition of terrorism in general, and a coordination of efforts to deter its occurrence.
