"People say to us, look, it may well be the case that there are fewer wars and fewer genocides, but surely more people are being killed. But when we look at this, the number of people killed in wars involving a state every year, all the wars, and you can see there's a high point, that's the Korean war, and it keeps on going down and down and down. If you look at the average number of people killed per conflict per year, it goes from 37-thousand in 1950 to just 600 in 2002."
