As an amateur war gamer and avid "imagineer" I'm going to define the upper limit of security potential for this event: this was a pot shot for bigger plans. RV VBIEDs are very cheap for nation states or proxies of them to afford and the time-resource cost of federal investigative powers to learn the truth is not designed for surgical, distributed, coordinated (multidomain) attacks with almost any violence of action. How can the FBI attribute without proving cases beyond a reasonable doubt? The real concern is where does it leave us comms wise? Weakened, dead? The whole country's comms taken out by 50 RVs? Go to war against who? With this sophistication have they critically sabotaged the military already? There's a clone army of shit beneath the waves and surface of America and our enemies are plotting, planning, developing, preparing, and waiting to strike in 0-36 days. We're all but asleep from it. Distracted. We can't manuever, communicate, run an economy or country. Done. Civil Unrest, death, invasion, USA completly falls from any resembling life as it was in 2 years, definitely a living hell no matter what going forward. Nukes and NBCE? Just shit. It's coming for sure.

House of cards shit.

Lower limit: Disgruntled 5G wack job.

Everything else in between is definitely serious. Why didn't DHS do anything about fortifying these installations by now?
