Access to internet is critical for Iranians. Starlink has been a digital lifeline, but can Musk be trusted to keep it on? The revolution will not be televised (see Gil Scott Heron). But we can hope it remains visible (see my "Space Citizens" Substack)

So much in Carney's speech was bang on,especially this "We knew the story of the international rules-based order was partially false that the strongest would exempt themselves when convenient...that international law applied with varying rigour depending on the identity of the accused or the victim"

What is the Asian Century? Have we already entered it? Why is space (satellites, data, connectivity) so important for this new era? My last post for 2025 is an enthusiastic rant, complete with a video of my visit to the Philippines for a regional gathering. Enjoy! open.substack.com/pub/spacecit...

While waging a murderous campaign in the Caribbean and threatening a war of aggression against Venezuela, the United States has now sanctioned two additional ICC judges for performing their judicial functions in the Palestine situation.

ICC strongly rejects new U.S. sanctions designations against two ICC Judges
The International Criminal Court deplores the announcement of new designations for sanctions by the US administration against Judge Gocha Lordkipanidze (Georgia) and Judge Erdenebalsuren Damdin (Mongolia). These additional designations follow the earlier designation of nine elected officials of the Judiciary and the Office of the Prosecutor, drawn from all regional groups.These sanctions are a flagrant attack against the independence of an impartial judicial institution which operates pursuant to the mandate conferred by its States Parties from across regions. Such measures targeting judges and prosecutors who were elected by the States Parties undermine the rule of law. When judicial actors are threatened for applying the law, it is the international legal order itself that is placed at risk.As previously stated, the Court stands firmly behind its personnel and behind victims of unimaginable atrocities. It will continue to carry out its mandate with independence and impartiality, in full accordance with the Rome Statute and in the interest of victims of international crimes.The ICC values the consistent demonstrations of solidarity of States Parties, civil society and all those who support the rule of law and justice for the victims of international crimes. The Court will continue its work, with all partners, to ensure the effective and independent implementation of its mandate.For more information, please contact the ICC Public Affairs Unit: PublicAffairs.Unit@icc-cpi.int. You can also follow the Court’s activities on Twitter/X, Facebook, YouTube, Instagram and Flickr

OK I am genuinely nervous about this but also excited. Just launched ep1 of my new podcast "Space Citizens" (yes the same name as my Substack newsletter). It starts with a bit of a rant, will include some awesome guests, and will probably be peppered with more rants. open.spotify.com/episode/6a4C...

Last week's Space Citizens substack was about the Artemis Accords. Because they turned 5 years old and now have 60 signatories. I can't help still being cynical, but maybe I have to resign to the fact that this is the guiding document for lunar activities. spacecitizens.substack.com/p/happy-birt...

As is often the case with international conferences, here at #APRSAF-31 in Cebu, Philippines, we are inside an expensive resort all day. But I walk from my accommodation to the venue past those Philipinos who built and work in the resorts, and see the other side of the coin

Literally brought me to tears. Ziptied kids together, put guns in the face of US citizens (no coincidence that these are black citizens) and explicitly dehumanise them, threaten them, attack their homes. I know this is going down, but to hear these eyewitness accounts made me cry.
