There is a Redditor who is “ex”-CIA, and a former Airman stationed at Malmstrom. He stated on here that he experienced silo shutdown related to UAP incursions while there, in a case that has not been publicized from what I’ve seen.
He did state that the official story from higher up was that they were testing some sort of need-to-know advanced drone, nothing to see here. And he is a former intelligence operative. But if factual, it confirms multiple decades of repeated nuclear shutdown related incidents at Malmstrom AFB.
I've read dozens of books and seen probably close to a 1000 interviews on this subject matter. The UFOs aren't too keen on us having atomic weaponry. As I understand it, the amount of energy released by nukes seems to mess up or leave a footprint in higher dimensional frequencies (4th dimension). This messes with their ships flight capabilities as they rely on the geomagnetic grid for various things (coordinates, etc).
They also think we're a primitive species, and are extremely unresponsible to have such weaponry. They don't want us destroying the planet because there is something they need here.
They're particularly responsive everytime we try to send a nuke into space. Theres numerous accounts of warheads going dark midflight as soon as they exit the atmosphere. Besides for nuclear fallout, there must be other reasons for them doing this.
