Large–scale indiscriminate violence has become the reality of contemporary terrorism. Terrorism is becoming a method of combat in which random or symbolic victims serve as an instrumental target. International law has no definitions of terrorism. The statement “one man's terrorist is another man's freedom fighter” is rather widespread and accepted. Victims of international terrorism are, as a rule, innocent victims, mass/collective victims, political victims and victims of crime and abuse of power. Some states are using terrorist organizations or individuals to promote state interests. The terrorists' secret weapon is suicide terrorism. No society can protect all its members from terrorist attacks, but all societies can reduce the risk of becoming the victim of terrorist attacks. Terrorism is a threat to fundamental human rights all over the world. As such it is negation of human rights concepts. This deals with obstacles in the human rights development process caused by present and/or potential acts of terrorism. Human rights concepts should not be understood in the narrow sense, namely only as a set of procedural safeguards for those suspected of terrorism, but also as a requirement for respecting the basic human rights of those affected by terrorist crimes. Some states are producing threats to civil liberties in three areas: government efforts to control debate and limit access to information, the incarceration of large numbers of people in a very troubling manner, and the rushed passage of an anti-terrorism bill. There are some myths and generalizations on terrorism. Are we facing a clash of civilizations along the lines Samuel Huntington (1) predicted? Some conclusions: it is necessary to de-legitimate terrorism, to fight the cult of martyrdom, to develop effective responses to terrorism, to facilitate inter-religious dialogue, to reduce vulnerability to future attacks, to improve the role of law and the International Criminal Court in the war against international terrorism.
