An EMP event could be one way to change government in North Korea without complete loss of life there

Whether this was done with a hydrogen bomb EMP 100 miles above North Korea going off it is one way to END for several months anything electrical ever working again in North Korea. It wouldn't kill everyone but could be one way to change governments there. The main problem would be that possibly Seoul also would not have anything electrical working for months too because of it's proximity to North Korea. And another problem might be cities near the Northern Border of North Korea in China also might not have anything working there either for months or years too.

But, if China and the U.S. agreed that this was a way for China and the U.S. to neutralize the present North Korean government this could happen because the alternative might be unthinkable.

This way conventional armies might be able to overthrow the Kim Jong Un government within a few days or hours. Because NOTHING electrical including cars, trucks planes, Nuclear weapons, NOTHING electrical there would ever work again until it was replaced from China or another country out of range of the EMP.

The main problem that I see with this idea is that anyone within 12 feet of anything metal likely would also die in North Korea caused by what might look like mini-lightning bolts off of anything metal inside north Korea. However, anything electrical not specifically designed to withstand an EMP would never work ever again (without being replaced by something built in another country not hit with the EMP.

So, anything that needs electrical components not to be all melted together and dysfunctional could not and would not work ever again in the whole country. This would be true of anything within 10 feet of the surface of the earth. IN other words anything not 10 feet or more underground that was electrical would be fused and melted beyond repair if it was electrical in nature after such an EMP hit.

An EMP is not used to destroy physical structures or people really (although some close to metal would die from mini-lightning bolts caused by the EMP.

Note: "EMP stands for Electro-Magnetic Pulse and can be caused by Solar discharges or Nuclear blasts in the sky or sometimes by smaller EMP generators like you might see in movies that take out a whole cities or part of a cities electrical components.

For example, a 100 megaton nuclear blast 100 miles up over the U.S. likely would end all electrical components in the continental United States until they were replaced by some from another country not hit by the EMP.

However, what would this do to the Atmosphere of earth? Would parts of the atmosphere leave earth and go out into space? This is unknown at present.

Another problem:

Where does the radiation go from such a blast to cause an EMP?

Likely this would travel around the world on currents of air wherever those winds took it over time.

The advantage of something like this is it can strike from space before anyone knows about it because it can go off 100 miles up and do it's job that way before anyone notices.

But, something like this likely would have to be agreed upon by China and the U.S. not to create a world war in using something like this. Either China or the U.S. or both together could do this to North Korea as long as China and the U.S. had some kind of agreement going on regarding all this.

The advantage of this is: Most people in North Korea don't die and Kim Jong Un is removed from power permanently.
