"Most studies of American foreign policy at the individual level focus on the president. Boucher, David, and Prémont very usefully direct our attention to the bureaucratic entrepreneurs in the National Security Council who try to drive change in the policy-making process, not always successfully and not always with positive results. This is a real contribution to our understanding of how American foreign policy is made." F. Gregory Gause III, Bush School of Government, Texas A&M University.
