With sincere and friendly sentiments, from a far-away land of the West Pacific Ocean , we would like to send this letter to all of you. It is written on the pending day of August 10th, when the US aircrafts, in 1961, began the spraying of herbicides in Vietnam with the northern areas of Kontum as their first target. The most recent investigative study conducted by American scientists  reported in Nature, April 2003, has discovered that  US forces, from 1961 to 1971 deployed about 80 million liters of toxic chemicals, more than half of which was agent orange containing nearly 400 kg of dioxin, an extremely  dangerous substance, to destroy our environment and human health. This horrible outcome was right from that time in 1960s, confirmed, warned and opposed by many prestigious American and world researchers such as Professor Arthur Galston, a biologist together with the US Physiobotanist Association and about five thousands (5,000) other US scientists, including seventeen (17) Nobel laureates and one hundred and twenty nine (129) members of the US National Academy of Sciences. We were deeply moved by pictures appearing on screens depicting hundreds of thousands of American people pouring into the streets against the war of aggression in Vietnam, especially pictures that showed American veterans throwing away their medals and awards after realizing the deception that had brought them to Vietnam to fight against a people who have aspired so much for independence and freedom.
