It is amazing that the leader most opposed to war was the Kaisar, who ended up watching as his country started one. And the leader most in favor of Slav rights was the Arch-Duke, who died by the hand of a Slav who wanted more rights. You've probably heard the saying about if you don't want the answer then don't ask the question........If you really want to know about every twist and turn of how Europe found itself in a world war then this is the book for you. But..If you wanted a concise discussion you've come to the wrong place.
To any student of history, professional or amateur, I would say read this book, it will open your eyes, but take it in small bites.
