Setting aside thoughts of mind-control, if people are being injected with large amounts of graphene (as seems to be the case), and that graphene settles into deposits in the brain, then a super EMP or even a mega solar flare could become a major concern, a super weapon that kills everyone without damaging property.

Here's a video of carbon (think graphene) self-assembling into wires, this could be done inside blood vessels of the brain under influence of an electromagnetic field. We know that there have been several shady things about the vaccine and virus being breaking the blood-brain barrier. https://www.youtube.com/watch?v=w1d0Lg6wuvc

Here's a related study about wires in the brain stimulating the brain. If the brain could be stimulated like this, then an EMP is a major concern. https://spectrum.ieee.org/implant-stimulates-brain-from-inside-a-blood-vessel

Here's a news article stating that Russia, China, and North-Korea have developed nuclear super-EMP weapons. https://ktar.com/story/4639134/the-era-of-space-warfare-and-the-growing-threat-of-emp/

I hope I'm wrong!
