"Whether Vietnam, Iraq, or now Afghanistan, wars come and go, but the real battle is a philosophic one between two sects of conservatives. In The Forty Years War: The Rise and Fall of the Neocons from Nixon to Obama, authors Len Colodny and Tom Shachtman challenge readers to examine the role of a little-known Pentagon figure named Fritz G.A. Kraemer. Colodny and Shachtman argue that Kraemer was the leading intellectual behind what became known as the neo-conservative movement, witnessed by the fact that Kraemer influenced so many high-ranking conservative figures over the course of six decades."
