The officially neutral country became a battleground in the
Cold War between the United States and Soviet Union, with American bombers dropping over

In Laos, the legacy of U.S. bombs continues to wreak havoc. Since 1964, more than 50,000 Lao have been killed or injured by U.S. bombs,
98 percent of them civilians. An estimated
30 percent of the bombs dropped on Laos failed to explode upon impact, and in the years since the bombing ended,
20,000 people have been killed or maimed by the estimated
80 million bombs left behind.
