International Campaign To Abolish Nuclear Weapons
Nuclear weapons pose the greatest immediate threat to survival, health, and sustainability. They are the worst weapons of terror. They poison human affairs, our bodies and the environment; consume vast resources; and threaten not only future generations but the future itself.
Any use of even one nuclear weapon would be catastrophic, and would pose profound and unpredictable risks of escalation. Use of nuclear weapons can never be justified, by anyone, anywhere, for any purpose.
