Lots of big talk on this thread.
Instead of talking, do some more reading. Start with the three books by Matt Bracken.
Then think about how those books in the context of today’s current events. It’s sobering.
Then consider that the state of intelligence gathering in the US is highly sophisticated - when it wants to be. Meaning that people shoot their mouths off on the Internet and think their postings are protected by a degree of anonymity. Okay...
I’m hopeful in real-life that people are a little more discreet about who they talk with. I’ve always found that 2-3 person teams (along with you) whom you absolutely trust can be a very effective and cohesive unit at work, etc. Any more than that and you often end up with people who like to blab rather than work, solve problems, etc.
Another contemporary book would be Unintended Consequences, by John Ross
