Today, at the Tu Du paediatrics hospital in Saigon, a former operating theatre is known as the "collection room" and, unofficially, as the "room of horrors". It has shelves of large bottles containing grotesque foetuses. During its invasion of Vietnam, the United States sprayed a defoliant herbicide on vegetation and villages to deny "cover to the enemy". This was Agent Orange, which contained dioxin, poisons of such power that they cause foetal death, miscarriage, chromosomal damage and cancer.

In 1970, a US Senate report revealed that "the US has dumped [on South Vietnam] a quantity of toxic chemical amounting to six pounds per head of population, including woman and children". The code-name for this weapon of mass destruction, Operation Hades, was changed to the friendlier Operation Ranch Hand. Today, an estimated 4.8 million victims of Agent Orange are children.

Len Aldis, secretary of the Britain-Vietnam Friendship Society, recently returned from Vietnam with a letter for the International Olympic Committee from the Vietnam Women's Union. The union's president, Nguyen Thi Thanh Hoa, described "the severe congenital deformities [caused by Agent Orange] from generation to generation". She asked the IOC to reconsider its decision to accept sponsorship of the London Olympics from the Dow Chemical Corporation, which was one of the companies that manufactured the poison and has refused to compensate its victims.
