You'll note the Prefabricated Faraday cages. Some people don't just roll over and play dead.
This section uses a HEMP protection effectiveness model based upon: IEC recommendations, known nuclear yields by nuclear-capable countries, and real-world testing of commonly used cables and equipment. This model was developed to better understand the ramifications of a HEMP attack and how much protection is needed to prevent damage or upsets (resetting the device). This protection would also be critical for SREMP and IEMI attacks. The model showed that even though minimal protection of 10 dB helps significantly, 20 dB is much more helpful, and 30 dB eliminates almost all damage.
The above is excellent news since 10 dB can often be met simply by following good lightning protection practices, including ensuring low inductance ground connections. 20 dB can generally be met and sometimes 30 dB can also be met by making small, inexpensive modifications. These EMP improvements include using EMP rated SPDs, adding ferrites, burying external cables, and moving operations toward the middle of a building perhaps in the basement with more walls between the cable runs and the potential HEMP burst.
These simple EMP related changes or additions could substantially reduce the risks associated with an EMP attack and prevent it from devastating the country.
In my forty year telecommunications career, I have worked in modern hardened facilities with equipment racks mounted in Faraday cage cabinets. Don't believe everything you see in the movies or on TV. There are people working night and day on The National Infrastructure Protection Plan (NIPP).

I’ve got radios wrapped in mylar static wrap in metal ammo cans. For all the good it’s going to do.
