“Why do they hate us?” The answer to a seemingly simple question made famous by U.S. President George W. Bush in the wake of 9/11 has become more complex with the entrance of homegrown terrorists into many armed conflicts. Why do they hate us so much that some of them try to kill us en masse, even though they are born and raised with us, go to school with us, and work with us. This book offers an in-depth analysis to the phenomenon of radicalization of second-generation Pakistani-Canadians. Based on interviews with second-generation Pakistani-Canadians from various backgrounds, Saad Ahmad Khan argues that radicalization is a complex and layered process stemming from multiple sources ranging from childhood experiences to the role of Saudi Arabia in exporting its brand of Islam. Individual, social, national, and international factors need to be addressed holistically, if radicalization of second-generation individuals is to be pre-empted and subsequent generations saved from the scourge of violence and terrorism.
