Your microwave oven is pretty good at attenuating 2.45 GHz signals.
That's a notch filter, though. Attenuation outside of whatever stopband the microwave door was designed for won't be nearly as good.
Very true.

The Ukraine conflict has frequently raised nuclear fears mostly due to Russian nuclear sabre rattling. But this has been happening since 2022 and it’s hard to see anything going hot anytime soon
Yeah, so how are we on the verge of nuclear war?

#173The book Nuclear War: A Scenario Hardcover by Annie Jacobsen should be essential reading for all politicians and those profiteering from the Military Industrial Complex https://www.amazon.com/Nuclear-War-Scenario-Annie-Jacobsen/d...
I read it and was not impressed. It starts with North Korea launching two ICBMs against DC and a nuclear plant in California. Interceptors fail and the warheads hit their targets. This is unlikely, but possible. The launch is explicitly irrational, the act of a mad dictator. In response, the US counterstrikes with Minuteman, despite having perfectly serviceable air deliverable nukes. Russia detects the launch, and th…
Russia may be kinda sorta next to North Korea, technically.
But you know who is really next to North Korea and has nukes? China.
It seems weird that Russia would even particularly care to be involved in this scenario, frankly.

We’re not. The author is just caught up in the threats/fear

#1751) Don't worry about it. If one goes off over a NATO country or Russia/China, you'll soon have much, much bigger problems to worry about. 2) There is no 2)

The current threat is actually for New York.

The New York region has recently been "declared as threatened". However, not by officials - this information comes from this session: https://rumble.com/v6sm22l-marina-jacobi-near-new-york-90-pr...

> The text of article 5 doesn’t distinguish whether the attack on the NATO state was justified or even whether the NATO state attacked first. Arguably, the text of Article 5 doesn't have to, since an act of aggression breaches the obligations of Articles 1 and 2, as well as the pre-existing obligations which the Treaty explicitly does not alter under Article 7.
I see what you mean - although articles 1 & 2 seem to be treated more like guidelines rather than rules. Otherwise I struggle to understand how any NATO member could’ve engaged in any of the overt or covert expressions of military force in Iraq 2003, Vietnam, Cuba, Iran, Guatemala, Chile, Egypt, or Algeria to name but a few.
None of the conflicts you list were NATO actions.
Re: What you need to know about EMP weapons
#178I'm not sure about most of this. The great majority of the articles and stories about this I've read trace back to layman speculation and disaster porn fiction written by people who have never claimed to actually be informed about how these things work. There's damn little stuff out there that traces back to actual experiments with real hardware. Probably most of the serious experiments are by various militaries and…
I happen to be from the same town as this guy. He is well known for building his own ramjet-powered cruise missile. I don't know about recently but he was actively involved in the local RC airplane club for quite a while if I recall correctly. His website is well worth checking out, he has a very extensive technical knowledge.
Okay, that's very cool! I don't mean to trash this guy at all, he may well be a real expert in some fields.
However, it is a failure mode that people who are really smart and qualified about one thing can assume they are equally smart and qualified about a bunch of other fields that require their own specific expertise. Alas, it doesn't work that way.
There's nothing wrong with not knowing about some specific technical subject. It is a red flag though when someone takes it as a threat to their identity and self-worth to acknowledge that they don't know much about some particular subject, even if they do know a lot about a different subject.

Here's congressional testimony on the topic from a top Pentagon Weaponeer named Lowell Wood, who I can personally assure you is well credentialed in this area. https://spp.fas.org/starwars/congress/1999_h/99-10-07wood.ht...
Note that this testimony is a persuasive presentation, an effort to persuade congress to allocate additional spending for EMP protection. Mr. Wood may indeed be qualified to speak on the subject, but this aspect necessarily colors his speech. It's not like there's a shortage of cases of decently qualified people exaggerating the risks of something in order to get more funding and status for themselves and their pet programs.
What I'd really like is hard data on what is or is not actually vulnerable to these hazards and to what extent, based on hard proof rather than fear-mongering by interested parties, which this doesn't get us any further towards.

There's plenty of unclassified info available. Start here.[1] This is an overview document from Defense Acquisition University, a unit of DoD. It's a painful PowerPoint. You have to plow through a lot of really boring military documents to get the details. EMP doesn't address small devices much. Small devices with no wires connected are not very vulnerable, because the energy is mostly at somewhat longer wavelengths,…
I did run through the whole thing. It doesn't actually say anything at all about what is or is not vulnerable, it's just a bunch of military standards and procedure about how to test for things and what to test, and some vague stuff about potential ways to protect things and what large military hardware they'd like to test.
Curiously, all of the links people have thrown out in this thread seem to prove exactly what I said - there's damn little available to the public in the way of documented experiments on real hardware for EMP susceptibility.
I don't have any really solid cites for it offhand, but it has been my understanding that small devices aren't vulnerable. I don't know EMPs specifically, but I have been involved in standard EMI testing for approval of consumer-grade electronics, so I know there's already a fair amount of testing for and shielding against EM interference with everyday consumer electronics.
