Abstract
Is the vision of global peace utopian, given that a record 22 wars killed an estimated 244 000 people in 1987 alone? This important issue is addressed from the perspective of a physician and medical educator. The paper focuses on the destructive powers of nuclear war and the biological, genetic and environmental consequences of ionizing radiation and the futility of the nuclear arms race. Priority is given to nuclear disarmament and the prevention of nuclear war. The effects of nuclear fallout, as well as concerns about nuclear energy, leaks and wastage are considered, and a global prescription for change is advocated.
