The goal of this paper is twofold. First, it attempts to explain why dispensationalist Christians were successful at influencing American foreign policy during the administration of George W. Bush, particularly towards the Middle East. Specifically, I connect this success to their ties to Washington neo-conservatives, the personal faith of Bush himself and his links to conservative Christians, and their broad cultural appeal and grassroots strength. Second, it will present two brief case studies on the influence that dispensationalism has had on US policy towards Israel and Iraq during the administration of George W. Bush.
