As for the drone sightings that are referenced later in this article: one interesting theory I saw is that these are drones launched by Chinese nationals under direction from the Chinese government. They are launched from farmland that is owned by companies or individuals affiliated with the Chinese government. The farmland happens to be near sensitive properties, such as military installations. And while it could be spying, it may also just be a test or just a way to create chaos. I’m not sure if this claim is true. But I did find other sources and evidence for the claim that there’s lots of suspicious Chinese owned farmland spread around the United States near sensitive properties.
