Well, I don't mean to be a cynic but waging wars is inherently tied to the human existence. There has literally never been a period in the history of mankind that was devoid of wars. Even now, in the 21st century we still wage wars. There will definitely be another World War. That I am certain of. The only thing that I don't know is when it might take place.

Cool art exhibit though. Kind of reminds me of the terracotta army.
