"The numbers give a sense of the scope. From 1964 to 1973, the United States dropped some 2 million tons of ordnance on Laos, the equivalent of one planeload every eight minutes, 24 hours a day, for nine years. It made Laos, per capita, the most bombed country in human history. In 1969 alone, the United States dropped more bombs on Laos than it did on Japan during all of World War II. All told, some 200,000 Laotians were killed in the war—about a tenth of the country’s population. Most were civilians. Nor did the end of the fighting in 1975 stop the killing; over the next four decades, unexploded cluster bombs would kill 20,000 Laotians and maim additional thousands."
