The term ‘regionalism’ has two connotations in the negative and positive meaning. In the negative sense, regionalism implies an “excessive attachment to one’s region to prefer to the country or the state”. When looked at its positive sense, it is “a political attribute associated with people’s love for their region, culture, language, etc.” by the view of maintaining the independent identity. 

Kenneth Waltz was the first scholar to use the three-level analysis methodology in foreign policy analysis. He has defined the three levels as images.

Classical Realism and Neo-realism as a whole body of Realist paradigm share some common assumptions that are key in understanding security in international politics. These common assumptions are: 1) International system is anarchic; 2) Power is the defining notion of state behaviors in the anarchic international environment; 3) States are the most important units/actors in international politics; and 4) States are unitary and rational actors. Choice A "International corporations are the most important units/actors in international politics." is not a common assumption of Classical Realism and Neo-realism. So the correct answer is A.

International organizations undertake a number of operational functions, including resource allocation, provision of technical aid, force deployment, etc.

As war is always a possibility among states, the anarchic international system, as Realists cite from Thomas Hobbes, implies a “war of all against all”. Mistrust is the common attitude of states towards each other in an anarchic international system and states cannot rely on any promises of other states or international institutions, but only on themselves, self-help (Terriff et al., 1999: 31-32).
