Although mainstream psychological theories provide a canonical framework for understanding terrorists' psychological history and functioning and for explaining how small-group processes facilitate the identity development and socialization of terrorists, they offer incomplete, decontextualized accounts of terrorism.  I argue that globalization produces sociocultural dislocation and psychosocial dysfunction which engender terrorism.  I outline three perspectives that serve to frame terrorism as resistance to globalization: social identity theory, social reducton theory, and Vygotsky's sociocultural theory.  I apply these theories to cases of domestic, foreign, and international terrorism.  I conclude by calling for the merger of positivistic and constitutive paradigms in order to achieve a more complete account of terrorism.
