To any clear thinking person it should be obvious that war is the final arbiter of all great conflicts. Those who speak of negotiated peace speak of fiction.
The great world wars have made this world what it is today, for better or ill, and there are numerous lessons to be learned regarding current geo-political conflicts. Thus I draw your attention to two very fine books.
Tuchman’s volume is about World War I, and Weinberg’s about World War II. Tuchman is a riveting popular historian who has the ability to tell a great story and make history come alive. Weinberg is more of an academic whose attention to detail, military and political, is simply jaw dropping.
An interesting theme crops up in both books that is both timely and intensely important.
Both Tuchman and Weinberg single out pacifists and peace movements and their murderous aftermath for special attention.
