Plausible deniability would certainly make for a tempting enabler - IF the attacker wasn't a stakeholder in the "New World Order". And yes, we are vulnerable to being set back centuries in short order.
But the cascading destruction of America, done to such a degree and at such a pace would be counter-productive to such stakeholders.
We are _already_ being reduced without EMPs. Look around and tell me which pillar of our culture and identify isn't already severely compromised. No EMP needed.
Some folks wonder, "what would an enemy do differently than is already being done to weaken America?". The obvious answer points to our current rulers _being_ the enemy. And what they are doing is as comprehensive as they can make it. Right under our noses. "Biden is weak", Biden is on the wrong track", etc... assumes that "Biden" is actually our President, working for us, working for America. This is but a quaint fantasy. No more fantastical than "Weak Republicans" needing to "grow a spine". As if they weren't simply one wing of the same corrupted, bloody-minded bird, determined to erase the power of an entire middle class.
EMPs? Nope. Zuckerbucks, MSM, BLM, FBI, Dominion...
Survival has steadily become more precarious as the sea we must swim in becomes ever more dependent on "social credit scores". The food, ammunition, supplies we have squirreled away? Critical. But only a fraction of the problem's solution.
