Literacy and War

The more literate the population and its leaders the less time in spent in war?  I think so.
 When an author doesn’t come out and say something but you can pick it up from the context alone, it’s clever.  Sometimes through an author and their writing alone, without spelling it out, we can determine what individuals or peoples or populations, etcetera, are literate and which are not. 

Reading of the American Civil War, I learn of the thousands of young men that deserted their schooling, either willingly, knowingly – or not. And of those, we have the approximate half of them that died, before their lives began, even before they had a chance to dream of a future.

What impact do you think that literacy had on the American Civil War and on populations throughout the world?
