Iran preparing nuclear counterproposal as Trump warns he is considering limited military strikes Iranian foreign minister says draft could be ready for internal review in coming days while US president says ‘they better negotiate a fair deal’

What is a ‘threat’ of force under Art. 2(4) UN Charter? My answer is in an article I published almost ten years ago in the Netherlands International Law Review: shorturl.at/GwGqQ

Rethinking Collective Self-Defence in International Law

A reminder of this event at ⁦‪ILaW :‬⁩ Rethinking Collective Self-Defence in International Law, 3 February, 6 pm www.westminster.ac.uk/events/rethi...

If you want to know whether Trump’s tariff threats are a violation of the principle of non-intervention, Chapter 3 of my book might be of interest. It explores what coercion is and whether economic coercion is unlawful under customary int’l law and the OAS Charter

From hackers to tech companies: IHL and the involvement of civilians in ICT activities in armed conflict Five key risks, and state obligations, when civilians become involved in information and communication technology activities in armed conflict.

Blog post by @icrc.org colleagues Tilman Rodenhauser (@trodenhauser.bsky.social), Samit D'Cunha, Laurent Gisel (@laurentgisel.bsky.social), as well as Anna Rosalie Greipl (@geneva-academy.ch) & @marcoroscini.bsky.social (University of Westminster).

I look forward to participating today in the launch of our report on civilian involvement in cyber and other digital activities in armed conflict, an output of the Joint Initiative on the Digitilisation of Armed Conflict of the @icrclawpolicy.bsky.social and the @geneva-academy.ch

I had two days of great discussions in Amsterdam on the AI-cyber interplay in armed conflict. I presented on Artificial Intelligence and the Obligation to Respect and to Ensure Respect for
International Humanitarian Law. Thanks to all the organisers and participants! #ihl #ai

I very much enjoyed recording this. Thank you for the invitation to share thoughts with these amazing colleagues

‘This excellent contribution will no doubt serve as the first port of call for any academic or practitioner looking into the subject.’ Thanks Jack Kenny for his generous review of my non-intervention book for @iclq.bsky.social

And just like that … the three-week residential session of the Hague Academy of International Law Centre for Studies and Research 2025 has come to a close—but the project is not over! Stay tuned for our forthcoming book on Artificial Intelligence and International Law

Today we kicked off the 2025 Centre for Studies and Research of the Hague Academy of International Law focusing on Artificial Intelligence and International Law. Exciting weeks ahead!

Delighted to be in Toronto to give a presentation on the principle of non-intervention as a balancing mechanism ensuring the co-existence of empires at the conference on Legal Histories of Empire: Empires in Touch #nonintervention

Another stop in the non-intervention tour. In 1968, Wenceslas Square in Prague became a focal point of resistance against the Soviet-led invasion of Czechoslovakia. After the Prague Spring was suppressed, Brezhnev proclaimed his doctrine of limited sovereignty.

‘The Author’s conclusions are well-supported by a thorough analysis of relevant international practice and scholarly literature. These qualities make the work an essential resource for anyone seeking to grapple with these themes’ Thanks A. Annoni for reviewing my book for Riv. dir. internazionale!

Does international humanitarian law address the problem of poverty resulting from armed conflict? My thoughts just published (in Italian) in the Proceedings of the 2024 Conference of the Italian Society of International Law #ihl #poverty #sdg

Another stop on the #nonintervention tour. The Nyon Agreement was signed on 14 Sept 1937. Nyon was chosen to avoid association with the League of Nations, which was viewed unfavorably by Italy. The agreement addressed attacks on international shipping during the Spanish Civil War

Did you know that, although never formally recognised by the Catholic Church, the monarchs of France, Spain and Austria claimed a jus exclusivae, ie, the right to veto a particular candidate to the papacy? See Chap. 1 of my book #nonintervention #conclave

Is the imposition of tariffs a form of economic coercion and an unlawful intervention in the domestic affairs of other states? Check out my recent book, pp. 170-186: shorturl.at/BvMsw #trump #tariffs #nonintervention

International law and the principle of non-intervention | UWE Bristol A RIPIL event featuring guest speaker, Professor Marco Roscini (Geneva Academy of International Humanitarian Law and University of Westminster).

See you tomorrow in Bristol or online #nonintervention www.uwe.ac.uk/events/inter...

Exclusive: US could cut Ukraine's access to Starlink internet services over minerals, say sources Ukraine's access to SpaceX-owned Starlink was brought up in talks between U.S. and Ukrainian officials after Ukrainian President Zelenskiy turned down an initial proposal from U.S. Treasury Secretary Bessent.

This looks a lot like economic coercion to me, prohibited by the principle of non-intervention (as codified in the UN Friendly Relations Declarations) and by Art. 3 of the 1994 Budapest Memorandum www.reuters.com/business/us-...

A call to make international humanitarian law a political priority ICRC President Mirjana Spoljaric outlines the pressing need for states to join the Global Initiative on international humanitarian law.

The growing normalization of violations of international humanitarian law poses an existential threat to int'l law.

We invite states to step up to their responsibility, reverse this trend & join our global initiative to reinvigorate political commitment for #IHL.

“The growing normalization of violations of international humanitarian law poses an existential threat to the Geneva Conventions and international law more broadly. This alarming trend requires urgent collective action.”
