Prompt
Generate a realistic image of a middle-aged American diplomat and academic in a formal setting, possibly in a office or a diplomatic reception. The man, Michael Armacost, is wearing a suit and has a dignified expression. He is likely in his 50s or 60s, with graying hair. Incorporate subtle hints of his notable positions, such as a US flag or a Brookings Institution logo in the background. The style should be a realistic portrait, with attention to detail and texture.
