You'll notice in the chart below that the latter part of the 1950's saw something of a lull in battle deaths per global capita -- a feat in human peace that would not be matched consistently until the 1990's. What would it take for the 1960's to be as relatively "peaceful" -- that is, for no year in that decade to surpass 1954 in battle deaths per person in the world?
