“…On July 26, 1947, President Truman signed the National Security Act, ending years of debate about the unification of the US armed forces. The Act inaugurated not only an unheralded change in the bureaucracy of the federal government but also formally institutionalized a new set of relationships regarding civil‐military coordination, mainly seen in the creation of the National Security Council (NSC), and (in 1949) the Department of Defense, that are key parts of what can be called the “national security state” (Yergin 1977; Hogan 1998; Stuart 2008a). On the face of it, explaining such a change should be straightforward in terms of conventional approaches in International Relations (IR) and its subfield of Foreign Policy Analysis (FPA): such a change was necessary to better provide for the national security and represented at best a rational (instrumental) solution to a present problem, or at worst a political compromise to deal with a clash of interested parties.…”
