Three key ques­tions for re­mem­ber­ing wars

Simcoe Reformer - Times-Reformer - - OPINION - GWYNNE DYER

“If they are not re­mem­bered, was the sac­ri­fice they made even worth­while?” asked an Amer­i­can vet­eran of the Iraq War who named his son after a fel­low sol­dier who was killed there.

This week we are asked to com­mem­o­rate the 100th an­niver­sary of the end of the First World War. That is no longer mem­ory; it is his­tory. The images are fa­mil­iar and some fam­i­lies have names and even pic­tures of rel­a­tives who died in the war, but very few peo­ple now alive knew them per­son­ally.

So how should we com­mem­o­rate the war? There’s not too much rhetoric about glory any more, thank­fully — we have grown up a bit — but a lot about sac­ri­fice. That’s a safe sub­ject, al­though the ma­jor­ity of the sol­diers who fought in the war had no choice about be­ing there.

How­ever, al­most every­body now re­al­izes that the First World War was a huge, point­less waste of at least 11 mil­lion lives. Many peo­ple knew that at the time. Yet no­body knew how to stop it then, and we in the present don’t re­ally know what to say about it.

The best use of the brief in­ter­val of con­tem­pla­tion about war on Nov. 11, there­fore, is to try to un­der­stand what kind of phe­nom­e­non war is.

Start with a sim­ple ques­tion: Where does war come from? The an­swer is equally sim­ple. Hu­man be­ings didn’t in­vent war; they in­her­ited it.

Our branch of the pri­mate fam­ily has al­ways fought wars. If there is an orig­i­nal sin, it goes back be­yond the time when the chim­panzee and hu­man lin­eages split five mil­lion years ago. (Chim­panzees still fight wars, too.) So for­get about the causes of war in the his­tory books. Ev­ery kind of hu­man so­ci­ety, with ev­ery kind of econ­omy, has fought wars.

Se­cond ques­tion: How did war get so big? The First and Se­cond World Wars were far more de­struc­tive than pre­vi­ous wars, and if the Cold War had ever turned hot, the Third World War would have been at least 10 times big­ger than that.

When the size and re­sources of a so­ci­ety grow, it tends to fight big­ger wars just be­cause it can. The is­sues at stake are not big­ger than be­fore, but los­ing a war is so un­ap­peal­ing that coun­tries gen­er­ally won’t quit un­til they have thrown all their re­sources into it.

And fi­nally, how can you tell when some stupid lit­tle thing like an as­sas­si­na­tion in Sara­jevo is go­ing to blow up into a world war? An­swer: you can’t. Which brings us to the Power Law. The Power Law de­scribes how so-called “crit­i­cal sys­tems” — ones that are in­her­ently un­sta­ble, and lock in more in­sta­bil­i­ties as time goes by, like those that pro­duce earth­quakes and for­est fires — are undis­crim­i­nat­ing about the scale of the event. Most will be on the smaller side, but you don’t need spe­cial causes to get a huge one: lit­er­ally any size of event can hap­pen at any time.

To know if a par­tic­u­lar class of events is sub­ject to the Power Law, you just graph the scale of the events against their fre­quency. If it turns out to be a straight re­la­tion­ship where dou­bling the size of the event de­creases the fre­quency by half — or makes it four times less likely, or 16 times, or any other power of two — then you are deal­ing with a crit­i­cal sys­tem.

In that case, you can for­get about seek­ing ma­jor causes for big­ger events. A ran­dom peb­ble is 16 times less likely to cause a huge avalanche than a lit­tle avalanche, but it can cause ei­ther.

Jack Levy, in a mas­sive 1983 study en­ti­tled War in the Mod­ern Great Power Sys­tem, mea­sured the size of ev­ery war in the past 450 years by its ca­su­al­ties, and found that dou­bling the size ex­actly halves the fre­quency.

This means that great wars do not need great causes. Once suf­fi­cient strains have ac­cu­mu­lated in a crit­i­cal sys­tem, a world war can strike out of a clear blue sky, as it did in the sum­mer of 1914. Or now, for that mat­ter.
