Thanks for the link Stag. I was familiar with his work but never saw this documentary. It is 3 hours well spent and I can recommend it to anyone familiar or not with his ideas.
Personally I do think that besides our geographic location, which gave us a head start for conquest, a genetic predisposition for aggression and/or violence might have been an important factor too. Eurasia is a region which has been at war constantly, probably as long as there have been inhabitants in that region and as a result, traits which benefited to that might have become the standard.
One wouldn't think so when looking at the current inhabitants but I do think we are bred to kill.
