Oppenheimer & Strauss: The Narcissism of Guilt
Throughout Oppenheimer, Lewis Strauss (Robert Downey Jr.) is consumed with paranoia regarding a brief conversation between J. Robert Oppenheimer and Albert Einstein beside a windswept pond in Princeton. Strauss assumes Oppenheimer poisoned Einstein's mind against him over an isotope export dispute.
The closing scene reveals that Strauss was entirely irrelevant to their discourse. Oppenheimer did not mention Strauss; he confessed his horror that the Los Alamos Trinity test had initiated an irreversible atmospheric chain reaction of geopolitical escalation.
The deeper motive dissected by the script, however, belongs to Oppenheimer himself. As Kitty Oppenheimer (Emily Blunt) savagely notes during his closed security board hearings: Oppenheimer submitted himself to public humiliation and political martyrdom not because he was powerless, but because he craved self-punishment to alleviate his cosmic guilt.
