Golden Dome's Space-Based Missile Defense Has a Physics Problem

This paper provides a physics-based rebuttal to industry proposals for space-based interceptors, specifically Booz Allen Hamilton's 'Brilliant Swarms' concept under the Pentagon's 'Golden Dome' initiative. It cautions policymakers that claims of low-cost, lightweight systems are unrealistic given the immense propellant mass required for boost-phase intercepts. The analysis suggests that pursuing such concepts as advertised could lead to costly investments in a system that is physically incapable of its primary mission and vulnerable to simple countermeasures.

AWS Built a Classified Cloud for Select Contractors. Northrop Is the First Test Case

AWS has launched a classified cloud environment tailored for defense industry workloads, naming Northrop Grumman as its initial confirmed user. The project aims to accelerate the development of sensitive defense programs, reducing the friction of classified IT infrastructure. However, the evidence for wider adoption or significant influence remains limited to this single customer deployment described by AWS executives.

Passchendaele: A Great War Village That Cost a Quarter Million Lives

The Third Battle of Ypres consumed British and German forces for over 100 days between July and November 1917, all to gain a few miles of Belgian mud. The offensive's true driver was not terrain but alliance politics: Britain needed to prove it could still attack while France's army was faltering.

Codex Desktop remote SSH/folders

I might be mistaken, but after today's app update, I'm able to edit remote folders—something that didn't work before. Is this a new feature, or am I imagining things? If it is new, congratulations!!!

DeepWeb AI Projects

I'm building an AI-powered OSINT tool to search, scrape, and analyze dark web (.onion) sites using Tor and Claude AI. I'm using Streamlit to interact graphically.

The core engine is running and it's generating tactical dossiers, but it's still evolving.

Components:

  • Infra & Privacy: Docker and the Tor network (SOCKS5 proxy) for 100% anonymous traffic.
  • Backend & Scraping: Python (FastAPI, LangChain, BeautifulSoup) with a local SQLite database.
  • Artificial Intelligence: Claude Sonet for automated reports, and ChromaDB for semantic searches.

Initial Phase yet. Tor Network is very unstable.

Is anyone else currently building projects focused on the deep/dark web?

AI Processes Faster. But the Button Needs a Conscience.

An AI can process targeting data in milliseconds, but research shows it still lacks intuition and moral judgment. These are not soft skills in national security. They are the human element of deterrence and alliance cohesion, the conscience required before the button is pushed.

Very good article!

Sharp slowdown in likes, restacks, and followers.

I'm quite regular with my posts and try to bring interesting and well-written articles, however, in the last month I've noticed a drastic decrease in the items mentioned above. It even seems like a kind of shadowban, similar to X. Have you noticed any changes?

Free OSINT library for defense and geopolitics: machines collect it, humans organize it. 318 docs, 17 sources.

Been quietly building this for a while. It's a real-time repository that automatically scrapes and parses open-access documents from global defense and intelligence sources.

Current state: 318 documents, 17 active agencies, categorized by Defense AI, Geopolitics, Hardware, History, Intelligence, and Tactics.

Sources include institutions like SIPRI and ISW. Everything is open access, nothing paywalled.

Filter by category or source. Updated automatically.

One note: every document links back to its original source and author. If you use anything from the library for research, writing, or analysis, please credit the original authors. These are researchers and analysts who put serious work into this material. The library exists to make their work more accessible, not to replace the attribution they deserve.
