During the Vietnam War, 25,000 barrels of Agent Orange were stored on Okinawa, according to a recently uncovered U.S. Army report. The barrels, thought to contain over 5.2 million liters of the toxic defoliant, had been brought to Okinawa from Vietnam before apparently being taken to Johnston Island in the Pacific Ocean, where the U.S. military is known to have incinerated its stocks of Agent Orange in 1977.
The army report is the first time the U.S. military has acknowledged the presence of these chemicals on Okinawa — and it appears to contradict repeated denials from the Pentagon that Agent Orange was ever on the island. The discovery of the report has prompted a group of 10 U.S. veterans, who claim they were sickened by these chemicals on Okinawa, to demand a formal inquiry from the U.S. Senate.
The army report, published in 2003, is titled "An Ecological Assessment of Johnston Atoll." Outlining the military's efforts to clean up the tiny island that the U.S. used throughout the Cold War to store and dispose of its stockpiles of biochemical weapons, the report states, "In 1972, the U.S. Air Force brought about 25,000 55-gallon (208 liter) drums of the chemical Herbicide Orange (HO) to Johnston Island that originated from Vietnam and was stored on Okinawa."
