Prompt
Create a realistic portrait of Paul Henry Nitze, a middle-aged to elderly American man with a dignified expression, dressed in a formal suit and tie, likely in a government or diplomatic setting. The image should convey a sense of authority, intelligence, and statesmanship, reflecting his influential career as a diplomat, politician, and strategist. Incorporate subtle hints of his association with Harvard University and his notable achievements, such as the NSC-68 document or the SALT talks. The style should be formal, realistic, and evocative of a bygone era of American politics.
