This video by Neil Halloran shows how many people died in the second world war, and what has happened in the world since (in terms of war deaths.) It really makes an impression, and is well worth the 18 minutes.
70 million people died during WWII, more or less (since the numbers, particularly on the Eastern front, are in dispute.) The video shows that most losses were suffered by the Soviet Union (the way the column grows and grows is heartbreaking, you just want it to stop) and China, that Poland had the most dead as a percentage of the population, that some individual incidents – massacres, battles, bombings – made for a surprisingly large portion of the dead. Stalingrad alone had more deaths than all wars since WWII combined.
The video has roughly the same message as Steven Pinker: That violence and war is on a downward trend, and that this is to be understood and appreciated. And, given these statistics, that giving the Nobel Peace Prize to the EU in 2012 perhaps wasn’t such a bad idea after all.
