ABSTRACT
The preceding chapters have discussed many of the characteristics of terrorism and active groups. There have been a great many terrorist organizations that have operated in the world. Different types of terrorist groups continue to operate. While much of the current attention is naturally given to Islamic groups, there are many other types of terrorist groups. There are terrorists linked to other religions, and terrorists from ethnic groups have also not disappeared. Right-wing groups continue to operate in the United States and Europe, and even some leftist groups remain active as is the case with the Naxalites in India. Over the course of time, terrorist organizations that have several types of objectives have appeared in many parts of the world. Even though it is true that many terrorist groups fail quickly, some survive to become meaningful threats. This concluding chapter on the overview of terrorism will summarize the key findings from the earlier chapters, but first there will be a reevaluation of the factors that have been considered to be causes of terrorism or that contribute to terrorism.
