2026 is a decisive year. States have a critical opportunity at the Seventh Review Conference of the Convention on Certain Conventional Weapons (CCW), on 16–20 November 2026, to move from discussion to negotiation on new international rules to regulate autonomous weapons systems.
The world cannot afford further delays in regulating autonomous weapons.
Learn more about autonomous weapon systems and why they should be regulated👉🏽ms.spr.ly/6017afS3l
ALT Without timely international action to set clear legal and ethical limits, there is a risk that unacceptable autonomous weapons will be developed and proliferate. Once such weapons are widely deployed, the risks to civilians and global security will be far harder to contain.

The one thing Donald Trump has been very clear about is that he would not use a nuclear weapon against Iran. (Support @PBS!)

In his capacity as the President of the First Review Conference of the Treaty on the Prohibition of #NuclearWeapons (TPNW), Ambassador @XolisaMabhongo convened a Stakeholders Engagement under the theme “Advancing the Imperative of Nuclear Disarmament: Broadening International Understanding of the Humanitarian Consequences of Nuclear Explosive Testing and Nuclear War.”
The #TPNW Stakeholders’ Engagement provided a platform for dialogue among government, regional and continental institutions, international organisations, scientific and academic experts and civil society to deepen understanding of the devastating humanitarian, health, environmental and socioeconomic consequences of nuclear explosive testing and nuclear war, while highlighting the enduring and intergenerational impact on affected communities.
Discussions also focused on the relationship between the TPNW, international humanitarian law and the broader international legal framework governing nuclear weapons.
 Our appreciation to the International Committee of the Red Cross #ICRC for their support in hosting this important engagement. @ICRC_SAfrica @ICRC_Africa @SarahMabeza

Pope tells governments to adopt a mandate to negotiate a new legally binding agreement at the CCW in November
Speaking to participants of a meeting focused on the future of AI, Pope Leo XIV stressed that decisions relating to human life can never be given to machines.
"Decisions affecting human life, freedom and the use of force must always remain subject to effective, informed and responsible human oversight. For this reason, artificial intelligence must be 'disarmed', and I encourage the States meeting in Geneva in November to take concrete steps toward banning lethal autonomous weapons."

Not a good move.
AI weapons are spreading fast, from drones to ground vehicles and submarines. Anna Hehir of Future of Life Institute @FLI_org warns that in a world this tense, it takes just one algorithmic error to spark a chain of events between nuclear powers.
She is also clear that a treaty would make a real difference. We never thought we would ban chemical and biological weapons, and we did.

If European leaders worry about Trump's retaliation if they invoke their blocking statute to limit Trump's sanctions against the International Criminal Court, they should remember their economic “bazooka,” which stopped his threats against Greenland. trib.al/ekZ8IV8

What happens when cartels get AI weapons?
“Imagine if there’s access to it by rebels, by terrorists. This will be a catastrophe.”
Dr. Lansana Gberie, UN Ambassador of Sierra Leone, Paula Peraza Aguilar, Costa Rican diplomat, and Alexander Kmentt, Austrian diplomat, warn that without rules, AI weapons won’t stay in the hands of states.

It’s still fascinating to hear people say “international law is useless” when the biggest military power in the world is this openly terrified of it.
Today, the Trump Administration is sanctioning the ICC.
This action should encourage our Allies within the Court to work for solutions to end this threat to U.S. sovereignty forever.

The UK stands with the International Criminal Court and we stand united with our partners in strongly disagreeing with sanctions imposed on the Court.
The ICC must be permitted to continue its critical work holding perpetrators of the most horrific international crimes to account.
ALT We, the undersigned States Parties to the Rome Statute of the International Criminal Court (ICC), reaffirm our continued and unwavering support for the independence, impartiality, and integrity of the ICC. As committed supporters of the ICC we regret and strongly disagree with the announcement of sanctions to be imposed upon the Court by the United States. If put into effect, these sanctions will have a significant impact on the Court’s work, its dedicated staff and their families. They work every day to bring those accused of the most serious international crimes to justice and to support their victims. We remain both united in our support for the ICC and committed to engaging in constructive and inclusive dialogue with non-States Parties as we prepare for the Assembly of States Parties in December 2026. We will continue to work together to support the Court’s vital work, uphold the rules-based international system, and advance accountability.

Hind Rajab Foundation is doing extremely important work, aiming to enforce international law around the world.
In a report by Swedish television, Israeli soldiers complain about our work at HRF and portray themselves as victims. They seem outraged by the idea that they could be held personally accountable for a genocide they continue to justify.
Watch till the end.

Come on, Canada! Join the conversation at the #TPNW review conference.
The Treaty on the Prohibition of Nuclear Weapons is supported by more than 100 countries, but not Canada.
I asked the government whether Canada intends to send an observer to the treaty’s first Review Conference at the UN in December.
I’ll be following up for an answer.

Vincent est allé interviewer des lycéens du IXe arrondissement de Paris. C’est un quartier privilégié il s’attendait à tomber sur des bourgeois ; au lieu de ça il tombe sur la réincarnation de Chirac, keffieh au cou, qui le déborde sur sa gauche avec du matérialisme dialectique.

A while ago I randomly watched Drive to Survive, despite motorsport being the most boring sport I could think of. I got hooked (& now I'm a cursed ferrari fan) It made me think, can we find a way to make UN negotiations a bit more interesting by letting people in on the inside?

UN conference rooms are not quite as glamorous as the Grand Prix in Monaco and drafting paragraphs is not perhaps as thrilling as an overtake at 350km/h. But I've been really fortunate to work with a group of talented people that are taking people behind the scenes at the UN
