I have found that in thinking about things geopolitically, I can cool my own rage and find, if not meaning, at least explanation for events such as these. As it happens, my new book will be published on Jan. 27. Titled Flashpoints: The Emerging Crisis in Europe, it is about the unfolding failure of the great European experiment, the European Union, and the resurgence of European nationalism. It discusses the re-emerging borderlands and flashpoints of Europe and raises the possibility that Europe's attempt to abolish conflict will fail. I mention this book because one chapter is on the Mediterranean borderland and the very old conflict between Islam and Christianity. Obviously this is a matter I have given some thought to, and I will draw on Flashpoints to begin making sense of the murderers and murdered, when I think of things in this way.
