Whereas most governments seek only those limited controls on weapons to which they agree, peace movements around the world have called for disarmament and totally getting rid of certain types of weapons, particularly nuclear, biological, chemical and antipersonnel weapons. Some groups and movements have pushed for complete elimination of weapons and armies. Peace movement campaigns have had some obvious successes, such as the banning of above-ground tests of nuclear weapons, and also have created a climate of opinion that has sometimes held back aggressive governments. However, peace movement campaigns have seldom dealt directly with the complex of scientific and technological operations serving military ends.

One exception to this is the movement for “peace conversion” or “economic conversion.”

Peace conversion is a vital part of any process of changing science and technology so that they no longer serve to sustain war and repression. But peace conversion can be only one part of this process, since it provides no alternative means of directly providing the security that is the stated rationale for, if seldom the consequence of, military forces. (The deeper driving forces behind military systems are discussed in chapter 2.)

One alternative to the military is nonviolent defence. The military option involves professional soldiers using specially designed instruments of violence to defend and attack. Nonviolent defence involves all concerned people using methods of nonviolent action such as rallies, refusals to obey, strikes, boycotts, sit-ins and setting up alternative institutions. As a full alternative to military forces, nonviolent defence is also called social defence, civilian defence, civilian-based defence and defence by civil resistance. From a nonviolence viewpoint, only some functions of the military — notably defending the core values of a society against attack — need to have a nonviolent replacement. A nonviolent defence system would not take up other functions of militaries, such as internal repression and threatening other societies.
