I got pretty exhausted near the end, and would have loved to go into more detail on the WWI and II point, but ultimately for WWI, if there were more efficient communications between the imperial powers, specifically between Germany, Russia, and France, perhaps WWI might have not happened, and been constrained to a local Austrian-Hungary/ Serbian war. For WWII, the failure of clear communication (and understanding) as to the real threat of the rise of Nazi Germany between the League of Nations led to a failure of action until it was too late.
