  Critical theorists, such as Robert W. Cox, also focus on the alleged inability of neorealism to deal with change. In their view, neorealists take a particular, historically determined state-based structure of international relations and assume it to be universally valid. In contrast, critical theorists believe that by analyzing the interplay of ideas, material factors, and social forces, one can understand how this structure has come about, and how it may eventually change. They contend that neorealism ignores both the historical process during which identities and interests are formed, and the diverse methodological possibilities. It legitimates the existing status quo of strategic relations among states and considers the scientific method as the only way of obtaining knowledge. It represents an exclusionary practice, an interest in domination and control.
