Having assessed the way in which both theories tackle the ground where there is greatest disparity between them, it can be concluded that neorealism improves on Classical realism to different degrees. It competently rejects human nature as a premise for international conflict, rendering the attempt to turn realism into a rigorous, quantifiable theory as successful, but posits an alternative that is also susceptible to scrutiny. Additionally, the neorealist assumption that states behave uniformly regardless of regime type seems to have varied levels of historical accuracy.
