Terrorism
In November 2004, a Secretary-General of the United Nations report described terrorism as any act "intended to cause death or serious bodily harm to civilians or non-combatants with the purpose of intimidating a population or compelling a government or an international organization to do or abstain from doing any act". The international community has been slow to formulate a universally agreed, legally binding definition of this crime. These difficulties arise from the fact that the term "terrorism" is politically and emotionally charged. In this regard, Angus Martyn, briefing the Australian parliament, stated,
The international community has never succeeded in developing an accepted comprehensive definition of terrorism. During the 1970s and 1980s, the United Nations attempts to define the term floundered mainly due to differences of opinion between various members about the use of violence in the context of conflicts over national liberation and self-determination.
Subversion
Offensive terror can be defined as the killing of people, destruction of property, kidnapping, etc. It is usually a minor part of subversion and, "is used not to exert force in the transfer of state power, but is meant to cower the people or ruler". Force used in this manner is meant to reinforce other forms or persuasion in addition to cowering the people or leaders. Additionally, much like civil unrest and agitation, it raises the question of whether or not the state can provide security for the population. Terror also provides a practical motivation of physically removing political opponents. The assassination of an organization's leader may open the door to a successor that is more friendly to the subversives position or possibly someone that has successfully infiltrated the organization and is in fact one of the subversives.
