THE QUIET AMERICAN- Graham Greene

Set in the dying days of Frances' Indochina adventure, Fowler, an aging British journalist and Pyle a young OSS/ CIA agent or similar come together over Phuong, lover to both men.

While the love triangle plays out we have Pyle offering covert support to Vietnamese military in an effort to stop the communist push. 

This book was published in 1955 and accurately predicts the disaster that Vietnam was to be for the United States.

Perhaps if monsters like Robert Macnamara had read this book , understood what Greene was saying many many young American lives would not have been thrown into the mincer that was Vietnam.
