Some thoughts from a veteran of political-science classes of the late 1970s. We learned of the difference between two foreign-policy realisms: classical and structural. Classical versus structural. Classical realists took the policy maker himself to be the chief object of interest/study. Machiavelli was the font of this approach. James Burnham was a self-conscious adherent. A classical realist won't talk, without qualifications, of a state (a city, in the font's context) as having goals, but will think of the people and factions who hold or are contending for power - a city's Prince or those who would be Prince -- have goals, and their goals become those of ‘the state’ when they achieve positions of command. Those decisions may involve deliberate absorption of the state by a neighbor, or even indifference as to whether the state survives or not. Structural realism speaks of states as having goals, determined by their history and systemic features of their decision maki
