Conventional Prompt Strike in European Military Power This research paper explores the critical role of conventional prompt strike capabilities in enhancing European military power.

New research by Dr Sidharth Kaushal argues Europe must use conventional prompt strike to degrade Moscow’s missile defences or risk the credibility of Britain and France’s nuclear deterrents.

Zero Knowledge (About) Encryption

I always assumed that #passwordmanagers were simple objects -- create a database, encrypt it, send it to the server, done. I could not have been more wrong!

At zkae.io, we take a look at all the hidden complexity in cloud password managers, and the #attacks that result from that. (ia.cr/2026/058)

The EU finally used an economic threat against Trump. But the markets forced his climbdown | Rosa Balfour While the threat of retaliatory measures to stop the annexation of Greenland worked, it remains to be seen if Europe has the unity to follow through, says Rosa Balfour, director of Carnegie Europe

Europe, too, can use economic leverage to its advantage.

What changed the U.S. calculus on Greenland was the threat of retaliatory measures worth up to $93bn, making the markets jittery & Trump fold, writes @rosabalfour.bsky.social in the @theguardian.com.

Meloni was wrong, Macron was right The Italian prime minister is trying to claim victory for Trump's retreat. But it was Europe showing its teeth through retaliation threats and troop deployment that spooked the US government.

EU prime ministers and presidents are about to arrive at the emergency 🇪🇺 #EUCO summit on transatlantic relations.

Europe's three camps - the hawks, appeasers and collaborators - are each trying to claim victory for Trump's retreat. Only one camp is right.

The Oligarchs Pushing for Conquest in Greenland Trump’s fixation on filching the island territory from Denmark may seem like the demented ravings of a mad king. But to a cohort of plutocrat weirdos, it makes perfect sense.

This is a must-read piece by Casey Michel on the underlying reasons for the Greenland nonsense and it should be getting more attention newrepublic.com/article/2051...

Can Europe Ever Trust the United States Again? In Donald Trump’s second term in office, the transatlantic relationship that helped define the postwar European project and global order appears broken. Is it time for Brussels to chart its own path?

Trump Pulls Out of Global Climate Treaty

The White House doesn’t care about environment, health or suffer of people. Peace, justice, cooperation or prosperity are not among its priorities.
Not even the great legacy of US to global governance.
And they spell it out.

The Cost of Europe’s Weak Venezuela Response International rules are only as strong as the democratic states supporting them. In the wake of the U.S. military operation in Venezuela, Europeans have a vested interest in making a compelling case for international law but shy away from doing so.

A functional country would shut Grok down permanently. Like, immediately. Right now. Last week. Whatever. Just flip the switch. Obviously.

These freaks want territorial expansion and they know Trump will do everything he can to deliver.

This isn’t just a tweet from some random asshole either. This is Stephen Miller’s wife. Miller was in the room with Trump during the kidnapping of Maduro.

The 🇺🇸 Deputy Secretary of State has today made your choice as a European very clear:

1️⃣Live in a vassal state of either America or Russia
2️⃣Live in a united federal EU

Which do you choose?

The headline, the main takeaway from a European viewpoint is this:

The transatlantic relationship as we know it is over. Yes, we kinda knew this. But this is now official US White House policy. Not a sppech, not a statement. The West as it used to be no longer exists.

I think Substrate is fraudulent: Part 1 Part 1 of an investigation into Substrate, a semiconductor firm that has garnered a lot of attention in recent weeks.

I wrote (but didn't proofread at all) open.substack.com/pub/foxchape... a post about why the semiconductor firm that's been all over the news is, actually, a fraud.

Lots of stuff the media didn't spot:

- The founder is a Kickstarter scammer
- He is apparently also solving nuclear fusion
- Nepotism

To give an example of what I mean, here's a paragraph from the Grokipedia "article" on ICE.

The three citations are to The Heritage Foundation, testimony from the Executive Director of FAIR, and a report from the Center for Immigration Studies.

No dissenting voices allowed on Grokipedia.
