This book is written in plain English for those who want to understand why there has been so much Islamic violence in the world and why this violence is increasing. Readers can ensure their understanding of the stark reality and degree of threat the non-Muslim world faces and prepare for it. Also, this book has not been written from a simplistic knee-jerk anti-Muslim perspective. For example, the first chapter concerns 'the problem at the center of ALL religions' and explores the single factor which makes religions generally social-conflict generators: unjustified certainty. After examining the Muslim contribution however, the book comes down solidly against Islam and provides much authority for its conclusions. This 2nd edition updates the first edition which was written pre-ISIS.
