Putin inside "command bunker" "near" Ukraine

People are ridiculing this setup. Bellingcat thinks this was filmed in a studio based on the audio and lighting. Others wonder why anyone would use camouflage netting to cover the inside walls of a bunker.

Poll: Europeans doubt they can defend themselves alone

source Poll: Europeans doubt they can defend themselves alone

A survey by Public First finds that Finland is the only country where a majority of people feel it is ready to fight alone. (Finland was the only exception, with a large majority of 76 percent confident their country was ready to defend itself.)

The Effects of High-Altitude Nuclear Explosions on Non-Military Satellites (2025)

Summary The detonation of a nuclear weapon at an altitude of 400 km will damage or destroy a significant number of satellites, depending on the detonation's location. The effects arise from both prompt radiation and delayed effects trapped electrons (Argus effect).

Prompt effects through X-rays, gamma and neutros:

  • A 15-kt detonation will place roughly 4 percent of LEO satellites at risk from prompt radiation.
  • A detonation of 110 kt or greater will place all LEO satellites within the line of sight at risk (roughly 20 percent of all LEO satellites).

With 300 kt explosion ionizing damage threshold is 12,000 km, SGEMP damage threshold 4,000 km

Delayed effects (Argus effect: high-energy electrons trapped in L-shells):

Effects on satellites:

  1. Lower-energy electrons can deposit on surfaces and exterior shielding, causing discharges that damage satellites.
  2. Intermediate-energy electrons penetrate shielding (deep dielectric charging).
  3. High-energy electrons can cause ionization and atomic displacements similar to high-energy X-rays and neutrons, destroying electronics (most electrons would be high-energy.)

>If a satellite has a design life of five years when exposed to 10^3 rads(Si), and a HANE exposes it to three orders of magnitude more, its life would be reduced by a factor of 1,000. This means its expected design life would fall to just a few days.

(note: linear degradation model where 1000-fold increase in radiation reduces lifetime 1000-fold is not realistic. Electronic component failure thresholds are non-linear. Many electronic components fail near instantly above specific radiation thresholds.)

Russia planning attack on Poland to test Nato resolve, US warns

>This could be presented by Russia as an accidental straying into Polish territory because of a GPS failure, or as a dubious rescue mission to retrieve a helicopter suffering from a malfunction.

>Russia would count on the fact that, instead of opening fire on Russian or Belarusian soldiers in such a situation, Poland would be forced by the US to negotiate with Russia or Belarus rather than respond forcefully

Sandia National Labs SA3000 8085 CPU

The SA3000 was used (and still is) in the W88 475kt nuclear warhead used on the Submarine launched Trident II.  It runs the main computer/programmer responsible for altitude and fuzing calculations.

Even the Secret Service won't use company-issued phones

Personal cell phones on protective missions, no threat detection on government-issued devices among the litany of sins.

The US Secret Service’s extremely lax mobile phone security practices - including using unsecured personal devices during mission operations - put America’s leaders’ and agents’ lives at risk, according to a government-issued report. https://www.oig.dhs.gov/sites/default/files/assets/2026-06/OIG-26-09-Jun26.pdf

"Secret Service agents’ phones can also reveal mission-related details, geolocation - and, by proxy, the US president, vice president, and visiting heads of state’s geolocations - as well as photos, contacts, and other personal information such as family members and home addresses.

It looks like Russian EKS early warning constellation doubles as a large-scale GNSS jammer.

The Russian Edinaya Kosmicheskaya Sistema (EKS) seems to be collectively responsible for wide-area interference, causing GNSS degradation for less than 10 seconds and dropping terrestrial receiver carrier-to-noise ratios by up to 10 dB. It affects all main GNSS systems: GPS, Galileo, BeiDou.

The theory is that the Russian early warning constellation doubles as a large-scale GNSS jammer. The Russians test the system's function periodically by sending short bursts. Signal degradations have not so far caused any problems.
