I thought since we were going to irrelevant times we may want to justify Iraq War #2 on these grounds as well (and then blame Clinton):
A good example of early chemical warfare was the late Stone Age (10 000 BC) hunter-gatherer societies in Southern Africa, known as the San. They used poisoned arrows, tipping the wood, bone and stone tips of their arrows with poisons obtained from their natural environment. These poisons were mainly derived from scorpion or snake venom, but it is believed that some poisonous plants were also utilized. The arrow was fired into the target of choice, usually an antelope (the favourite being an eland), with the hunter then tracking the doomed animal until the poison caused its collapse.
