Interesting article at Slate.com by John Horgan arguing that war may not forever be a part of human society:
A recent decline in war casualties—especially compared to historical and even prehistorical rates—has some scholars wondering whether the era of international war may be ending.
Counting casualties is fraught with uncertainty; scholars’ estimates vary according to how they define war and what sources they accept as reliable, among other factors. Nevertheless, a clear trend emerges from recent studies. Last year, 25,600 combatants and civilians were killed as a direct result of armed conflicts, according to the 2009 Yearbook of SIPRI, the Stockholm International Peace Research Institute, to be released Aug. 17. Two thirds of these deaths took place in just three trouble spots: Sri Lanka (8,400), Afghanistan (4,600), and Iraq (4,000). In contrast, almost 500,000 people are killed each year in violent crimes and well over 1 million die in automobile accidents.
If nothing else, it does put things in perspective a bit and points out that really, things are not getting worse and worse.
