Humanity's stupidest war

One hundred years ago today, the Austro-Hungarian Empire declared war on Serbia, beginning what probably was - from the standpoint of the reasons behind it, the incredible death and destruction wrought by it, and how it caused an even more devastating war only two decades later - the stupidest and most unnecessary war in the history of humanity. The Atlantic's Burt Solomon describes World War I, and what it has meant for humanity in the century since it began:

It was a sad, pointless war, for which we’re still paying a price. A hard-hearted peace treaty and a ravaged economy produced a “lost generation” of young Germans and led directly to the rise of Hitler and an even uglier worldwide conflagration. The secret Sykes-Picot Agreement reached by Britain and France in 1916 drew arbitrary boundary lines across the postwar Middle East—around Iraq, for instance—that are returning deadly dividends to this day. The toppling of the Russian monarchy and the collapse of the Austro-Hungarian Empire created a balkanized Europe that, as recently as the downing of Malaysia Airlines Flight 17 over strife-torn Ukraine, pains us still. The world was a nastier place after the war than before it.

All wars tell us something about the basest regions of human nature, the First World War (caustically named in 1918 by an English journalist who thought it would not be the last) more than most. About the nature of covetousness, the perils of insecurity, the ease of losing human control over human events.

It's been said that conflicts on the scale of World Wars I and II will never happen again, due to the invention of nuclear weapons and their associated premise of mutual assured destruction. I'm not convinced, especially given the presence in today's world of nihilistic fanatics - e.g. jihadists - who don't care if they're destroyed, just as long as their enemies are annihilated as well. Aside from that, there is the primal and emotional nature of our species that sometimes tends to overwhelm our ability to reason, even in the face of unspeakable destruction. Solomon concludes:

Indeed, evidence is slim that we’ve grown wiser since the war intended to end all wars did nothing of the sort. Still, if it’s any consolation amid the tragedies and disorder of today’s world, Homo sapiens have been way stupider in the past than they are right now.

And if you haven't already seen it: if World War One was a bar fight.
