I think our minds are gonna be blown.
As one matter, I believe millions in America were subjected to MK Ultra Trauma Based Mind Control since that all started after WWII especially with Mengele coming here under Operation Paperclip. (He later likely became Dr. Green, reportedly). So we have millions of individuals in America who have multiple personality disorder, Monarch & other programming and all the other problems associated with that horror show. Then there are the SRA victims, which can be classified as one group, but then MK Ultra overlaps into SRA so that's one heck of a mess. Then, on top of that, we have IMO a BIG soul-less entity problem such as ETs posing as Humans, clones & Vril, & clones may be either AI controlled or demon possessed or both (something has to fill the void, right?) and all those abominations have no conscience and likely also huge pedophile & vampire appetites.
Basically I think the "infiltration" JFK warned us about was this mind blowing mess.
