Resumen de Another world war could still be on the cards
Since 1945, the world has been--comparatively--peaceful. Some believe this "long peace" is the start of a new, conflict-free era. But a recent analysis suggests it is just a blip, and a major war could be around the corner. To see if we truly have turned a corner, Aaron Clauset at the University of Colorado in Boulder studied wars that took place between 1823 and 2003. He used data from the Correlates of War project, which gathers data on conflicts. Over the 181-year period, there were 95 wars: one every 1.91 years on average. Clauset measured the size of each by comparing the number of soldiers killed. The second world war was the worst, killing 16.6 million. He defined a large war as one in the top quarter by military casualties. Clauset split his study period into three. In the first period, prior to the first world war, there were 19 large wars, one every 6.2 years. But the long peace since the second world war only saw five, one every 12.8 years
