This is a very good sign that our movements for the abolition of nuclear weapons and the negotiation of a Nuclear Weapons Convention are making a difference. There are literally thousands of chemical and biological weapons in storage and some in hiding. Weapons of mass destruction have an interdependent relationship. Because Israel has nuclear weapons, Iraq says it felt threatened and justified in creating a biological weapons program. Where both countries got the technology to create these weapons is easily answered.
Biological spores know of no borders and can be carried by the wind very easily.
The Biological Weapons Convention entered into force in 1972 and was the first international agreement providing for a genuine measure of disarmament. It prohibits the development, production, stockpiling, and acquisition of biological weapons, and mandates their destruction. Unfortunately, it does not have a verification regime. The Chemical Weapons Convention entered into force in 1992. Both Conventions have stigmatized these weapons.
