Write to, phone or meet with decision-makers in your country to seek their support for the total abolition of nuclear weapons.

Since 2017, thousands of parliamentarians across the political spectrum have responded to the demands of concerned citizens and signed an ICAN pledge to promote adherence to the Treaty on the Prohibition of Nuclear Weapons (pledge.icanw.org).

Hundreds of cities, from Washington DC to Paris to Sydney, have also formally supported the treaty, signing onto an ICAN appeal (cities.icanw.org).

You need not be an expert to make your voice heard. What matters is that you recognise the gravity of the threat and the urgency of action.
