This video featuring John Green focuses on 'War and Human Nature' and is part of the Crash Course in World History educational series. This episode provides a ten-minute discussion which looks more philosophically at whether humanity is naturally warlike, hard-wired to kill, or whether perhaps war is more of a cultural construct.

Watch the video and let us know your thoughts about war, human nature and the relationship between the two.
