HUh, it would set us back, but not that long.
Yes we would be vulnerable to a secondary incursion, (or they would be “invited”, but The us military and unfortunately our ‘guvernmunt’ would still function as they are “hardened-shielded’ from EMP.)
we could retaliate against any nation invading us (if US wanted to that is)
But against a peon country like NORK, if we hit back it would bring China into it as they are NORK allies.
The real danger will come from our own Govt. inside CONUS after an attack....what will they do to us patriots???
It would set us back at least 2 generations. Most of the technical fields would have to be recreated from scratch. With people who are in diapers right now. It would take at least that long to have enough computer engineers, electrical engineers, physicians, nurses, and other specialized persons to reach where we are today.
Those fields would be decimated, literally, when the big cities go up in smoke. Most big teaching and R&D hospitals? In the big cities. Most really big engineering firms? In the big cities. Most pharma R&D in this country? Outside Indianapolis, in Northern New Jersey, and a few places along the Eastern seaboard. All near, or in, large cities. AT&T has a lot of engieering and techie types in Northern NJ. In Salinas KS? Not so many there...
