Almost all of the longer range ballistic missiles, and several types of land-attack cruise missiles, carry nuclear warheads. Most of these warheads have an explosive force that is tens to hundreds of times more powerful than the atomic bomb dropped on Hiroshima during World War II. Chemical and biological weapons are attractive to many Third World countries because they are much easier to produce than nuclear weapons. Many countries with chemical and biological warfare programs also are equipped with ballistic and/or cruise missiles. Accuracy is not very important for these weapons when used against urban areas or large concentrations of military forces. Chemical and biological weapons are capable of producing massive casualties, inducing panic and chaos in civilian populations, and severely degrading military operations.
