>I've wondered if its related to the fact that a real game of poker cannot be played without something at stake... a bot has no desires or fears about the future no attachment to the prize.
I don't think that's the obstacle. It's only a math problem for a bot--just a really, really, really, really hard one that hasn't been solved yet.
>I am kind of surprised that an expert considers war and poker to be so different, both seem to be games of limited information where something real is being contended
The difference is that two very simple observations about war (that it is costly and that you can bargain over the issues at stake) allow you to say a ridiculous amount about conflict. Unfortunately, those useful shortcuts don't appear to be helpful in poker.
>Is there a book you know of that give a popular science account of how game theory is applied to war by governments?
I wrote one a couple years ago, based off my notes for intro to international relations: http://www.amazon.com/Game-Theory-101-Rationality-War-ebook/dp/B008X12GIW/ref=la_B007JMSDR4_1_4?s=books&ie=UTF8&qid=1402290707&sr=1-4
