"The phenomenon of terrorism" (by Vilen Ivanov) looks into the crucial aspects of the phenomenon of ter¬rorism such as its notion, origins, and reasons for its activation both globally and in Russia. A mention is made of a recent all-Russian survey among both general population and experts aimed at measuring reactions to cur¬rent terrorist attacks. As for subjective roots of the phenomenon, nationalism and religious extremism are cited along with right- and left-wing ideologies. New configuration of forces in the world, aftereffects of the Cold War, alliances of terrorist groups with drug dealers, and organized crime are duly discussed. International co¬operation as a means to fight terrorism is pled for, La., between Russia and the USA, as well as Algeria, Egypt, India, Indonesia, and Israel Income cleavage in Russia is discussed in this context, too.
