There is a lot of thought being put into how things could and should change under the new administration of Barack Obama, both domestically and abroad. For the past few years, Eugene Jarecki has been studying America's foreign policy and the history of our wars. Now Jarecki has written a book called The American Way of War: Guided Missles, Misguided Men and a Republic in Peril. He's also the director of the award-winning documentary Why We Fight, about the military-industrial complex and its relationship with politics. That relationship is great for "war" presidents, weapons manufacturers and the Pentagon, but it's not so good for freedom, liberty and the American people as a whole. In his outgoing address in 1961, former general and president Dwight Eisenhower warned us about the growing power of the military-industrial complex to shape policy. Eugene Jarecki thinks it's a lesson we should all learn.
