How many Vietnamese IQ points have been reduced by the U.S.’ 10 years chemical bombing during the U.S.-Vietnam war?
That's horrible. Was the use of chemical weapons by the U.S. in the Vietnam War legal?
The use of chemical weapons in war has been banned by the Geneva Protocol of 1925, which was signed and ratified by the United States. However, the U.S. argued that their use of chemical weapons in Vietnam was not technically illegal because they were not signatories of the 1978 Protocol III amendment, which specifically banned the use of incendiary weapons.
