What is terrorism?

Terrorism is the use of terror in the form of violence or threats to force an individual or group to accept the demands of terrorists. Terrorists intentionally destabilize the society and the state through acts of violence like kidnappings or attacks. In their opinion they are waging a war for freedom. For instance, in the Basque region in Spain the ETA has killed more than 800 people in its struggle for an independent state in the past 40 years.
