Terrorists mean frighten and thereby intimated a wider audience, such as a rival ethnic or religious group, an entire country and in its political leadership, or the international community as a whole.

Terrorists typically attempt to justify their use of violence by arguing that they have been excluded from, or frustrated by, the accepted process of bringing about political change. They maintain that terrorism is the only option left to them, although their choice is a reluctant –even a regrettable one.

At the time terrorist acts –including murder, kidnapping, bombing and arson-have long been defined in both national and international law as crimes. Even in times of war, violence deliberately directed against innocent civilians is considered a crime.

Terrorism has occurred throughout history for a variety of reasons. Its causes can be historical, cultural, political, social, Psychological, economic or religious-or any combination of these.

Some terrorists are motivated by very specific issues, such as opposition to legalized abortion or nuclear energy, or the championing of environmental concerns and animals rights. They hope to bring under pressure both the public and its representatives in government to enact legislation directly reflecting their particular concern national governments have, at times, aided terrorists to further their own foreign policy goals.

Terrorism motivated by religion has frequently led to acts of violence with higher levels of fatalities than the relatively more targeted incidents of violence perpetrated by many secular (non-religious) terrorist organizations.

Another key factor that has contributed to terrorism-rising deadlines is the ease of access to a range of low-tech and high-tech weapons.

An increase of suicide attacks has also contributed to terrorism-rising death count. Suicide attacks differ from other terrorist operations, because the perpetrator’s own death is a requirement for the attack’s success. Suicide bombers, therefore, are typically high motivated, passionately dedicated individuals, who decide voluntarily or upon persuasion, to surrender their lives n fulfillment of their mission.

Terrorists today claim credit less frequently for their attacks than they once did, the current trend toward less communication implies that terrorists today may use violence simply as vengeance or punishment rather than as a means to achieve political change. Therefore, their actions require no explanation or justification outside the terrorist group itself or its supports.

The future terrorism

Terrorism has existed for al least 200 years and is likely to remain a fixture on political agendas, both domestic and international, for the years to come. Terrorism provides a means by which the weak can confront much stronger opponents.

Terrorism, moreover, is constantly to overcome governmental counter –measures designed to defeat it.

Terrorism thus involves an ongoing search for new targets and unidentified vulnerabilities in its opponents. This quest also raises the possibility that terrorists may pursue unconventional means of attack, such as chemical, biological, radiological (radioactivity-spreading) weapons or nuclear weapons. Future terrorist tactics could include cyber terrorism (sabotage using computers to destroy computer networks or systems) or electronic warfare that targets critical infrastructure, such as communications and power facilities societies in general.
