"The Fallen of WWII": What is your biggest takeaway after seeing this video?

The Fallen of World War II is a uniquely interactive documentary that examines the human cost of the second World War and the decline in battle deaths in the years since the war. This 15 minute data visualization provides a new perspective on the scale of conflict in recent years and really made me stop to think about the sheer size of war we may never see thanks to the greatest generation. I can't help but be saddened by this video, but also reminded that our freedom is here because of tremendous sacrifice from those who came before us. After watching this, what is your biggest takeaway and how do you see wars continuing to evolve during our lifetime?
