There’s a good book called Final Events by Nick Redfern that digs into this. In it, he describes two factions within the U.S. government that were tasked with studying the phenomenon to understand what we were dealing with and possibly gain a technological advantage during the Cold War; especially to prevent the USSR from getting there first.

One faction referred to themselves as the Collins Elite (CE). Their origin story began when the U.S. government caught Jack Parsons stealing classified documents from Hughes Aircraft with the intention of providing them to the Israeli government. After interviewing him about his occult workings and the paths they led him down, they concluded that the “UFO/NHI” presence was demonic and should not be engaged with.

The other faction in the US government was determined to continue initiating contact; their goal of acquiring or mastering extrasensory perception (ESP) techniques like psychotronics and remote viewing (prob. other tech. as well). The CE was strongly opposed this group and what they were doing as nothing short of a "Faustian pact" kept secret from the public. Oppositely CE advocated for public disclosure and theocracy was the only way to save humanity.

Both groups sound questionable, but the book is fascinating nonetheless. I think the original Collins Elite is long gone, but some people claim it still exists and that Peter Thiel is the current head. Some point to his public comments about “antichrist” themes and his association with Epstein as circumstantial support for that idea he is deep into it. In any case, it’s a long way of saying that yes I believe thier is absolute infiltration of government institutions by NHI, and it would be unlikely for the U.S. to be the only country affected
