The Vietnam War ended 40 years ago, but left a deadly legacy, especially in Laos. The US military dropped more than 2 million tons of bombs on the country during the war between 1964 and 1973, making Laos the most heavily bombed country in the world on a per capita basis. There were more than 580,000 bombing missions on Laos, equivalent to one bombing mission every eight minutes, 24 hours a day, for nine years. Not all of those bombs did what they were supposed to do. An estimated 30 percent of ordnance failed to explode, remaining live in the ground years after the war. They continue to detonate at unexpected places and at unexpected times, such as when children are playing.
