Historically, the USA foreign policy has been directed by the doctrines of deterrence and containment, which provided for the USA intervention in international affairs only as a way of deterring or containing events that are of a possible threat to the USA economic, political, social, and security interests. First, the doctrine of deterrence was applied as the major approach to the USA foreign policy in the period immediately after World War II (Microsoft Corporation, 2004:n.p.). The doctrine of deterrence applied the continued investment of the USA in nuclear weapons and other weapons of mass destruction, as a strategy for deterring the USSR attack, considering that the two nations had emerged as the major world powers after World War II. Following the collapse of the USSR in 1991 that left the USA as the only superpower, the foreign policy doctrine of containment was adopted by the USA, which combined diplomacy and conventional military strength to protect the USA interests in the international spheres (CRF, 2015:n.p.). Nevertheless, all these had to change with the entry of President George H. W. Bush into office in the year 2000, which marked the rise of a new USA foreign policy approach that characterized the Bush Administration 2000-2008, popularly known as the ‘Bush Doctrine’ (CRF, 2015:n.p.). .
According to the neo-realism theory of international relations, states interact on the international front on the basis of anarchy, where the major intention of each state is to maximize its power relative to the other states (Waltz, 1986: 333). Further, this theory holds that states act on the international front in accordance with the logic of self-help, which means that states are purely focused on meeting their own interests while interacting with others on the international front, and they will not subordinate their interest to the interests of the other states (Baldwin, D. (1993:27).
