Apart from the methods used and the extent of the violence, however, war and terrorism are also seen differently by international law.
The differences are not always clear-cut and even experts may disagree about whether a violent campaign counts as terrorism, civil war, insurgency, self-defence, legitimate self-determination, or something else.
All of the above led to a general atmosphere of fear: a state in which people could no longer feel secure from the threat of arbitrary violence.
From such beginnings, the concept of terrorism entered the vocabulary.
These years were characterised by the use of violent methods of repression, including mass executions authorised by the Revolutionary Tribunal, a court set up to try political offenders.
Towards the end of this era in particular, people were often sentenced only on the basis of suspicion and without any pretence at a fair trial.Terrorism is another of those terms that everyone seems ready to use, but no-one can agree on an exact definition.Even the experts continue to argue about the way the term should be applied, and there are said to be over a hundred different definitions of terrorism, not one of which is universally accepted.Wars and national emergencies allow for states to "derogate" from – or temporarily put aside – some of their human rights commitments.However, certain human rights, such as the right to life or the right to be free from torture, inhuman and degrading treatment can never be put aside.These are regarded as so important and so fundamental that they should be observed even when a state's security is at risk.A judgment of the European Court of Human Rights in 2011 (Al-Skeini and Others v.Question: In the 20th century, Chechens, Abkhaz, Kurds, Palestinians and Irish Nationalists have all seen themselves as fighting a war against a colonising nation.Nation states have always regarded the actions of such groups as terrorism. Wars are sometimes defined by the fact that they take place between nation states: but where does that leave civil war, or the so-called "War on Terrorism"?An act of terrorism normally has an end goal which is "bigger", and more strategic than the immediate effect of the act.For example, a bomb attack on civilians is meant to change public opinion in order to put pressure on the government.
