And, unless I misunderstand, an EMP is non-discriminatory. It will impact ALL electronics (unless hardened to withstand such).
Reduces the chances the Chinese (or anyone else) will actually use one in a fight, in my humble opinion. Why blind your opponent if you’re also going to be blind and dead in the water?
There are ways to protect from EMP. I won’t go into details but they have existed since we first detected them.
