Nonsense. If you watch TV or read the papers you'd think world conflict is just around the corner and everyone is fighting everyone. Not true.
Last year a carefully researched Human Security Report concluded that the numbers of armed conflicts in the world had fallen 40% in little over a decade, and that the number of fatalities per conflict had also fallen.
The entire news agenda for a decade, received as endless tales of wars, massacres and bombings, actually missed the key point. Things are getting better.
Percentage of males estimated to have died in violence in hunter-gatherer societies was about 30%. Percentage of males who died in violence in the 20th century (including two world wars and a couple of nuclear bombs was approximately 1%.
The trends for violent deaths so far in the 21st century ae falling sharply too. Let's hope it stays that way.
