Reminder: aggression does not to be preceded by a cross-border use of military force. This is the lesson from countries which has had foreign military bases: Panama 1989, Ukraine (Crimea) 2014, and maybe Denmark (Greenland)? See below, article 3(e) in UNGA Resolution 3314(XXIX).

Why does it matter that Nicolás #Maduro told a US judge he’s still president of #Venezuela? International law prohibits prosecution of a sitting head of state in another country’s courts. @keitnerlaw.com explains head of state immunity and the Maduro case: www.justsecurity.org/128073/head-...

TAPPER: Can you rule out the US is going to take Greenland by force? MILLER: Greenland should be part of the US. By what right does Denmark assert control over Greenland? The US is the power of NATO T: So force is on the table? M: Nobody is gonna fight the US militarily over future of Greenland

For the past two years, I have enlisted colleagues in U.S. academia to write a book on Litigating International Crimes and Human Rights Violations in U.S. Courts. Today, I did my second review of the chapter on “Jurisdiction and Immunities,” drafted by David Stewart, Georgetown Law. Timely stuff.

Maduro’s case will revive a legal debate over immunity for foreign leaders tested in Noriega trial

That means Maduro & Venezuela can invoke that Maduro has personal immunity against arrest, criminal investigation & prosecution. If US judges don't recognize such immunity (or that Maduro is the president of Venezuela) it opens up for other states to act similarly, potentially against US interests.

The US on protection of heads of state: “in addition to immunity from criminal jurisdiction, heads of state, heads of government, and foreign ministers ... also benefit from personal inviolability, a protection that informs their treatment in the criminal context.” legal.un.org/ilc/sessions...

During Fiona Hill's testimony to Congress on Oct 14, 2019, she described how Trump and Putin discussed exchanging Ukraine for Venezuela. The quid pro quo was if Trump refuses to help Ukraine fight off a Russian invasion, Putin would not help Venezuela (a Russian ally) resist a US takeover.

Jag får flera frågor angående USAs Venezuela-intervention från de som anser att MR och demokrati ska gå före suveränitet. Jag hade sådan uppfattning fram till 2003. Se två nedanstående inlägg där mitt skifte framgår, först från februari 2003. klamberg.blogspot.com/2003/02/tidn...

⚡️The Moscow City "Court" convicted the ICC Prosecutor & 8 sitting/former judges of "unlawful prosecution" of Russian citizens (because one of them got so upset). ICC officials were sentenced in absentia (keep it that way!) to jail terms of 3.5-15 years. Karim Khan received 15.

Undra om Sida upplever att riksrevisionen ger motstridiga instruktioner? Tre år mellan nedanstående granskningar. Riksrevisionen 2022: "Sida motiverar inte tillräckligt sina prioriteringar och internationella samarbeten i redovisningen" Riksrevisionen.2025: "Sidas processer är onödigt krångliga"

Beyond all other illegalities Hegseth's order to kill survivor's in the water is a crime which implicates all US personnel. If Hegseth's policy would be generally accepted, future US navy personnel shipwrecked would also become lawful targets. www.washingtonpost.com/national-sec...

This is surreal: 'despite the plausible legal framework, the OLC opinion relies on a fact pattern about the cartels for which no public evidence appears to exist.' We'll be teaching this in the 'how not to do international law' parts of our courses for years to come.

Busy day today, attending PhD seminar in Uppsala (before lunch), moderating debate on abducted Ukrainian children in the parliament (in the afternoon) and launch of my new book (in the evening). Thanks to all of you who contributed, organised and attended!

DNs @sannabjorling.bsky.social skriver Ukraina aldrig kan gå med på kravet om amnesti för ryska förbrytare.

10 januari samtalar jag med @klamberg.bsky.social i Stadshallen i Lund om hans nya bok om folkmord.
