The Peloponnesian War by Thucydides. Something that should be mandatory in High School Social Studies (since we no longer teach history), but isn’t probably because it would scare people into actually killing our current batch of politicians.
Want to know how our democracy is going to be viewed 2000 years from now? Here you go. Brutal, cynical and fascinating. The scoundrels live, the good guys get screwed over. There is no justice in the world. Not then and not now.
My comrade took his name from this book. I was tempted to take Thucydides as mine, but I have always had a fondness for Talley.
