query: What was the court's ruling regarding the use of herbicides and defoliants in Vietnam in the Agent Orange case?
answer: The court ruled that the use of herbicides and defoliants in Vietnam was not intended to poison humans, but to destroy plants providing cover for the enemy, thus classifying it as herbicidal warfare.  The court also cited the British use of Agent Orange during the Malayan Emergency to dismiss claims against the chemical companies.
