Nuclear risk reduction is not a substitute for disarmament; it complements and reinforces existing commitments.

80 years ago, nuclear weapons were used for the first time. Today we remember the victims of the bombings at Hiroshima and Nagasaki.
But nuclear risks are on the rise again. Any miscalculation or failure could be catastrophic.
A nuclear war cannot be won and must never be fought.
๐จ๐ญ calls to:
๐น Strengthen the #NPT
๐น Reduce nuclear risks
๐น Re-build trust between nuclear powers
