Answer: No, The Quiet American is not based on a true story, but it is inspired by real historical events and figures.
Explanation: Graham Greene’s novel The Quiet American is a work of fiction. However, it draws heavily from the political and social climate of Vietnam during the 1950s. The characters and specific events are fictional, but they are set against the backdrop of real historical events, such as the French colonial rule in Vietnam and the early stages of American involvement in the region. The novel reflects Greene’s own experiences as a journalist in Vietnam, and it critiques the political and moral complexities of foreign intervention.
