Recently, the US interpretation of the Biological Weapons Convention has come to reflect the point of view that Article I, which forbids the development or production of biological agents except under certain circumstances, does not apply to non-lethal biological weapons. This position is at odds with original US interpretation of the Convention. From the perspective of this original interpretation, current non-lethal weapons research clearly exceeds the limits of acceptability defined by Article I. The following documents contain expressions of this original interpretation, and highlight how the current US stance breaks with historical precedent.
President Nixon's Statement
On November 25, 1969, several years before the BTWC was negotiated and signed, the US stance on biological weapons was articulated in a unilateral statement made by President Nixon in which he said:
"I have decided that the United States of America will renounce the use of any form of deadly biological weapons that either kill or incapacitate."
President Nixon's Message to the Senate on Ratification of the Geneva Protocol
In this message, President Nixon states:
"In submitting this Protocol for approval, I consider it desirable and appropriate to make the following statements:
The United States had renounced the first-use of lethal and incapacitating chemical weapons.
The United States has renounced any use of biological and toxin weapons."
The National Security Archive, through Freedom of Information Act requests, has received several declassified Nixon administration documents that reflect the US government's position on biological weapons at that time:
The Biological Weapons Anti-Terrorism Act of 1989 is the implementing legislation for the Biological Weapons Convention. After being passed it was incorporated into Title 18, Part I, Chapter 10 of the US Code. In Section 178 of Chapter 10, a biological agent is defined as:
"any micro-organism, virus, infectious substance, or biological product that may be engineered as a result of biotechnology, or any naturally occurring or bioengineered component of any such microorganism, virus, infectious substance, or biological product, capable of causing death, disease, or other biological malfunction in a human, an animal, a plant, or another living organism; deterioration of food, water, equipment, supplies, or material of any kind..."
