All war is based on deception.
The Art of War was written about 2,500 years ago in China by Sun Tzu. But it is one of the most famous military treatises written because it is the oldest surviving one and quite possibly the first one ever written. For interested readers, the Art of War is available free online through Project Gutenberg . In my opinion, a good player of the game of Diplomacy must not only be a good diplomat, but a good strategist. Because I see the two as being strongly enmeshed, when I heard about Sun Tzu's Art of War , I was very interested in reading it to see if I could find principles that apply to the game of Diplomacy in a 2,500 year old document.
