All through this week including yesterday, 22 January 2026, ICAN partners marked the five year anniversary of the nuclear ban treaty with actions, lectures, film screenings, discussions and demonstrations. Follow #5YearsTPNW on social media, or check out highlights below.
Over the last few days, and continuing through the weekend, ICAN partners and allies have celebrated the Treaty on the Prohibition of Nuclear Weapons as a hopeful light in what seems like an otherwise dark time for the world. We’ve heard about activities across at least three continents marking this important milestone in the history of abolishing nuclear weapons. From governmental meetings, to public roundtables, demonstrations and discussions, people gathered to build momentum against nuclear threats.
Building public opinion
Many of our partners also took this opportunity to publish opinion pieces - including in Norway, Belgium, Italy, France and Germany.
The International Trade Union Confederation put together this great video message:

Parliamentary advocacy
In the Netherlands and the US, campaigners briefed parliamentarians on the increasing risks of nuclear weapons, and the Treaty on the Prohibition of Nuclear Weapons as a way to reduce those risks, while the Australian Red Cross seized the chance to “reiterates its call for all remaining States, including Australia, to sign and ratify the TPNW and join the global movement to eliminate the threat of nuclear weapons once and for all.”
Here are some highlights from around the world:

The action targeted L3Harris for its role in producing equipment for nuclear-armed missiles and surveillance systems, as well as supplying weapons used in Israel’s attacks on Gaza, and followed a series of protests by the Demilitarize Western Mass coalition at the company’s local facility.
