EMP 101

Lately I've been giving some serious thought as to how God's word describes those who come against Israel in these last days on horses.
I wonder, is it possible,is this going to be the new post EMP world where all modern day techonology has become a thing of the past ?
Or is it as I've heard for decades, The writers never saw mechanized transportation and could only relate them to armies on horseback ?

An EMP attack is different since it only requires but one nuclear weapon, detonated 300 miles above the middle of the United States. One bomb. The launch could even be done from a container ship somewhere in the Gulf of Mexico and in that instant, the war is already over and won.....
Unless you are in a jet liner, plummeting to earth, or caught in a massive traffic jam of stalled vehicles on the interstate, you might not even know anything has changed.
Sure the power is off, but we've all been through that dozens of times.
You call the power company. But the phone doesn't work and that might be slightly more unnerving. You might go to your car to drive around and see what happened and then it becomes more unnerving when the car does not even turn over, nor any other car in your neighborhood.
Twelve hours later the food in your freezer starts to thaw, if it is winter and you don't have a wood stove the frost will start to penetrate in to your house, if summer and you live in Florida your house will be an oven. And that will just be the start.
Law enforcement will be powerless without radios, cell phones, and squad cars, unable to know where there is a crisis and how to react. The real horror show within hours will be in hospitals and nursing homes. They're required by law to have back up generators, but those generators are "hot wired" into the building so power can instantly kick in if the main system shuts down. That "hot wiring" means the Electro Magnetic Pulse will take out the generators and their circuitry as well
If you are familiar with what happened in New Orleans after Katrina, multiply that ten thousand times over to every hospital and nursing home in America. Nearly everyone dependent on life support equipment in ICUs will be dead within hours. Nearly everyone in nursing homes dependent on oxygen generators, respirators, etc., will be dead or dying while depending on the time of year temperatures within plummet or soar.....
Our interstate highways will become nightmare paths of exile as our largely urban population tries to fan out to find food that once was shipped in.
Millions could and will die on that road. Where do they get safe water? The nearby stream or river is now a dump for raw sewage since purification plants are off line. Once stricken on the road by the results after drinking this water, where does one get help, basic medication, more water to keep you hydrated.
