A 10kt nuclear bomb going off at 400 mi. altitude over CONUS is in fact the end of the world, or a close approximation.

Best to kill these things as they begin their ascent, if you can.

It would take at least 4, detonated exactly together, at a precise altitude and in a rough diamond formation. And a lot more than 10kT, the classic example, the Starfish test, was 1.something mT.

With the use of fiber optic cable in telecommunications, the EMP problem is less of an issue than it may have been even 10 years ago.

A more likely event is a CME that causes massive problems with the power grid. We got a taste of this Mar 13, 1989.

Tho I will be the first to say a nuke detonation in your city will ruin your day...

“..10kt nuclear bomb going off at 400 mi. altitude over CONUS is in fact the end of the world,...”

Sorry, but that statement is so misinformed that I must say something. I presume you're talking about EMP effects, but a 10 kiloton bomb ain't going to do it! The sun sends more EM energy at that altitude! Just a reminder, Hiroshima and Nagasaki were taken out by @17-18 kiloton weapons.

They've THEORIZED that a 100 MEGAton could wreak havoc on our telecommunications and solid-state equipment, but that's NOT the end of the world!

You would need multi-megatons, not 10 kt. A 410 kt detonation affected aircraft 190 miles away. Covering the whole US would need much more energy.
