Ban Ki-moon Grave Quotations

Any use of chemical weapons, by anyone, under any circumstances, is a grave violation of the 1925 Protocol and other relevant rules of customary international law.

Grave security concerns can arise as a result of demographic trends, chronic poverty, economic inequality, environmental degradation, pandemic diseases, organized crime, repressive governance and other developments no state can control alone. Arms can't address such concerns.

We must eliminate all nuclear weapons in order to eliminate the grave risk they pose to our world. This will require persistent efforts by all countries and peoples. A nuclear war would affect everyone, and all have a stake in preventing this nightmare.
