The historical context of the United States leading up to the Civil War illustrates the challenges faced in creating a unified federal authority amid deeply rooted societal differences.

Oppenheimer is noted as the initial postwar realist to criticize Einstein for what he perceived as excessive idealism, contrasting the pragmatic approach of realists with Einstein's more aspirational views.

The struggle for cohesive authority in the face of ideological divisions serves not only as a historical lesson but also reflects ongoing debates about idealism and realism in contemporary thought.
