Only the past 60 years or so. And in death counts, mainly. This is largely due to a few factors, but most importantly, we don't just line up accross from each other, run and kill one another. Technology, planes, bombs/missles, drones, satellites, radio and tv feeds, and even the Geneva Convention have added to this. The number of conflicts isnt really down globally, it rises and falls of course, but the number of deaths and scale of them is. For now....
