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

@UNIDIR side event at #NPTRevCon showed broad support for risk reduction. Timely discussion of what🇨🇭🇨🇳🇿🇦🇬🇧 and others hope to see reflected in an #NPTRevCon outcome.

Opinion: There's a ground-breaking deal that Trump and Putin could actually reach in Alaska: nuclear arms control, write @SahilV_Shah and @KomissarWhipla. https://t.co/MR3AIAGty2

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.

🇨🇭 calls to:
🔹 Strengthen the #NPT
🔹 Reduce nuclear risks
🔹 Re-build trust between nuclear powers

It’s been my priority from the very start to run a process that moves us step by step, piece by piece, towards convergence.

I have done so in good faith, and relied on your good faith, to make the process work.

The next hours are critical. #Revcon4
