re: Russian High Altitude Electromagnetic Pulse (HEMP) weapons.

Seems like they could have prevented a lot of Russian deaths if they had used such devices in Ukraine, no?

nahh. the threat of mutual destruction is the only REAL preventative.

missile defense isnt stopping a multi pronged attack or even a 5 missile barrage with 4 dummies.

we'd know who launched them and retaliate (in a sane world) even if it was after we'd been hit.

are there nations out there that may think it's worth it? that I don't know. but I could definitely see a rogue nation making a deal with a bigger power (NK & China maybe) to roll the dice.

You want russia to go nuke on ukraine?
You sure?

Faraday Cages, my house is 95% shielded.

It's easy to do.

Yippeee, youve shielded all your elctronics but have no electricity to use them.

How would we know if they did or not?

Almost 20 yrs ago it was estimated that during an EMP, about 10% of the vehicles on the road would come to a stop. I'm sure that is a far higher percentage now.

Old vehicles are better, including older tractors, off road motorcycles etc.

Batteries should be fine, like AA etc.

Things connected to the grid are vulnerable. If you have a device that is charging, it's gone.

Things with solid-state technology will go down.

I have no idea about aircraft - seems a lot of those systems would go down, but who knows.

Main power grid will go down - recipe for chaos.

Allegedly, if your vehicle has any of the following, it will be rendered inop: electronic fuel injection,
anything computerized that controls your vehicle’s main systems, a PCM (also called a powertrain control module), ABS (Anti-locking Brake Systems) electronic ignition or keyless ignition, or a negative battery terminal that is grounded to the vehicle frame. I don't understand the battery terminal part and why that makes a vehicle vulnerable.

Oh, and here's a blurb I found about electric vehicles (even more reason to shun these things):
Electric cars are particularly vulnerable to EMPs since they rely on electronic components for both their operation and charging.
The battery, motor, and other components can be easily damaged by an EMP, rendering the car inoperable. Though the battery itself will likely survive an EMP (assuming it is not plugged in and charging) so many of the components that make these cars function will not make it, unfortunately.
Even if the electric vehicle is not destroyed by the EMP, it will likely be stranded if the infrastructure needed to charge it is also destroyed. Electric cars are a luxury that will not be an option in a post-EMP world.
In short, a vehicle that relies heavily on computers, solid-state switching, and other such intricate electronic components is highly vulnerable to an EMP as first- or second-order consequence.
Any vehicle that is plugged into a charger or other electrical grid is doubly vulnerable to the
effects of an EMP.

"Smart homes" will go down in an EMP attack.

The electronics on portable generators are said to be vulnerable, making them useless post-EMP.

Electronics involved in public water supply will probably be damaged. So...no water, or no clean water.

Computers and similar devices will probably be toast, immediately.

People with pacemakers - those things might stop working.

Most CB radios, hand held radios, flashlights and similar gadgets will work, unless they are connected to the grid for charging, when the EMP hits.

Basically an EMP will put society into chaos. But, why spend money on that when we can just give that money to the teacher's unions, right?

Non nuclear EMP.

It's hard to believe the US military has any huge and decisive advantage over China or Russia in a pure technological sense. The Chinese and Russians have had a shite ton of college students in our best STEM universities for decades and both governments have obtained a lot of technology from US corporations as a condition of allowing US corporations in China and Russia.

They're really good little worker drones, but they have no gift for innovation. The Chinese economy is based on copying other people's shite and reproducing it. They invent almost nothing.

Communism doesn't respect or create innovation. Quite the opposite.
