In the database CTC follows the international common accepted definition of terrorism.
Terrorism is 'the use or threatened use of violence against people or the causing of serious damage to property that disrupts daily life, with the aim of bringing about social change or influencing political decision-making'. (see also: Definition of terrorism on NCTV-website). Counterterrorism refers to all practices, tactics, techniques, and strategies that governments, militaries, and other groups adopt in order to fight terrorism. The state has several instruments in fighting terrorists. First, police forces. Secondly, the army. Third, judicial instruments and fourth, political and socio-economic instruments.
CTC also follows the definition of radicalization given by the National Coordinator for Counterterrorism and Security (NCTV) which describes the expression as a social process. Radicalism is: 'The active pursuit of and/or support for fundamental changes in society that may endanger the continued existence of the democratic order (aim), which may involve the use of undemocratic methods (means) that may harm the functioning of the democratic order (effect).
The NCTV distinguishes two types of radicalization processes. First of all, there are radicalisation processes that constitute a direct threat to the democratic order. For example, the attempts of violent jihadists, such as the supporters of the Takfir Wal Hijra ideology, to radicalise young people and recruit them to their cause. Secondly, there are radicalization processes that do not constitute a direct threat to the democratic order. These include missionary-like Dawa-oriented groups, such as the Salafists and the Muslim Brotherhood, which have opted for a long-term strategy of continuous indoctrination based on highly puritanical, intolerant and fiercely anti-Western ideas. They preach extreme isolation from Western society and often propagate intolerance towards other groups in society. In addition, they encourage Muslims to covertly develop parallel social structures.
