America's Secret War (2017) documentary

While the United States was publicly engaged in the Vietnam War, a secret conflict was raging just next door in the country of Laos. Under the command of the CIA, a full-blown military operation engulfed Laos, with a select few of the U.S. Armed Forces participating. At Long Tieng, a secret airbase in the heart of Laos, the CIA trained an army of allied guerrilla fighters including a large number of the Hmong people (an ethnic group from the mountainous regions of southern China, Vietnam, Laos, Myanmar, and Thailand), to assist in destroying enemy supply lines. The hour-long documentary AMERICA'S SECRET WAR uncovers the history of this covert war through the stories of Hmong elders and a rich collection of never-been-seen archival images, maps, and documents, including recently declassified CIA intelligence
