Every state's attitude towards fighting terrorism, therefore Serbia's too can be regarded on several levels. The first level relates to the actual terrorist threat a particular state is facing, the second level refers to the state's capacity to oppose terrorism, and the third level is the public perception of terrorist threat, and the state organs' strategic determination towards fighting terrorism. When talking about the terrorist threat to Serbia, we must look at a wider picture that shows the problems of the whole southeast Europe region, which is an aggregate with regard to the issues of security. The fact that the same criminal and terrorist groups threaten all countries in this region with terrorism and organized crime is the key factor that links them into a single security network.
