Neoclassical realism

Neoclassical realism is a theory of international relations and an approach to foreign policy analysis. Initially coined by Gideon Rose in a 1998 World Politics review article, it is a combination of classical realist and neorealist – particularly defensive realist – theories.

Neoclassical realism holds that the actions of a state in the international system can be explained by intervening systemic variables, such as the distribution of power capabilities among states; cognitive variables, such as the perception and misperception of systemic pressures, other states' intentions, or threats; and domestic variables, such as state institutions, elites, and societal actors that affect the power and freedom of action of the foreign policy decision-makers.

Overview
While holding true to the realist concept of balance of power, neoclassical realism adds that states' inability to perceive one another accurately, and/or state leaders' inability to mobilize state power and public support, can result in suboptimal foreign policy, the rise and fall of great powers, and war. There are four variations of a state's balancing behavior:


 * Appropriate balancing occurs when a state correctly perceives another state's intentions and balances accordingly. Neoclassical realists disagree whether this optimal behavior is fairly standard or actually quite rare. Ripsman, Taliaferro and Lobell suggest that whether states correctly perceive their international environment may depend, for example, on the relative level, clarity and directness of existing threats.
 * Overbalancing occurs when a state incorrectly perceives another state as threatening, and uses more resources than it needs to in order to balance.
 * Underbalancing occurs when a state fails to balance, out of either inefficiency or incorrectly perceiving a state as less of threat than it actually is.
 * Nonbalancing occurs when a state avoids balancing through buck passing, bandwagoning, or other escapes. A state may choose to do this for a number of reasons, including an inability to balance.

According to Nicholas Ross Smith of University of Nottingham Ningbo China, Neoclassical realism has primarily been criticized for its "apparent ontological and epistemological incoherence". A 1995 study criticized Neoclassical realism for encompassing "nearly the entire universe of international relations theory" and stretching realism "beyond all recognition or utility." According to Stephen Walt of the Kennedy School at Harvard University, one of the chief flaws in Neoclassical realism is that it "tends to incorporate domestic variables in an ad hoc manner, and its proponents have yet to identify when these variables have greater or lesser influence".

Neoclassical realism has been used to explain a number of puzzling foreign policy cases, such as the volatility in South Korea-Japan relations, Fascist Italy's foreign policy, Slobodan Milosevic's decision-making during the 1999 Kosovo crisis, the occurrence of the Cod Wars between Iceland and the United Kingdom, and Iran's foreign policy choices after the American invasions of Afghanistan and Iraq. Proponents of the theory argue that the theory is particularly valuable in explaining cases that fly in the face of other international relations theories, due to its incorporation of domestic variables.
