The Dangerous Lie of Numbers - The Vietnam War

In April 1975, the last American helicopters lifted off the roof of the U.S. Embassy in Saigon, ending one of the most controversial wars in American history.

From Afghanistan's collapse in 11 days to the information warfare being waged on social media today, McNamara's ghost still haunts the modern battlefield. 👍 Like and comment to help keep these stories alive.
