Recently, the world has witnessed arbitrary acts of terrorism and violence carried out by various individuals and/or organizations. The significance of studying terrorism - whatever the focus in such a potential study is - lies in that numerous international legal principles that are firmly established in international treaties or conventions have now become subject to controversy or - at least - have lost their practical value owing to different reactions vis - à - vis this phenomenon.

Undoubtedly, many studies have explored the phenomenon of terrorism in order to decipher the main motives behind its spread and to furnish relevant, appropriate and effective remedies. These studies, however, have been politically influenced, and therefore, were hindered and have become unable to arrive at a clear and neutral definition of terrorism.

The study highlights the significance of finding a definition of terrorism. It also deals with the attempts which were made to define terrorism through international treaties and UN resolutions.

The study further shows that despite the attempts referred to above no success has been witnessed in terms of constructing a clear, definition of ‘terrorism’. The persistence of the ambiguity surrounding the concept of ‘terrorism’ will always remain a stumbling block that hampers any endeavor to reach a comprehensive and effective way of objectively tackling this phenomenon and that impedes the various efforts made worldwide in this direction.
