''Psychosocial Stress in Immigrants and in Members of Minority Groups as a Factor of Terrorist Behavior'' deals with the universal phenomenon of immigration in the light of globalization and the double messages of host countries. On the one hand immigration is encouraged and on the other hand the rights and obligations of newcomers in a country are not always clear. Creating a theoretical link between concepts and terms allied to immigration and terrorism is based on worldwide evidence from the last eight years. The aim of the contributions in this publication is to understand more and shed more light on the etiology of terrorism and on what has to be done to prevent it.This book addresses the underlying issues that lead to lethal actions which have led to the loss of the lives of so many innocent people and its mission is to discuss and understand more comprehensively the relationship between immigration and terrorism. Learning more about psychosocial stress in immigrants, who arrive in a new country and have expectations that are not met, will highlight new angles that policy makers have not previously attended to.
