Long ago, as a kid, I read a book written by a defector from the Soviet Army. It's still an interesting book, I recommend it.

There's a chapter in it about leadership lessons he learned. One is that threats are a sign of weakness, not strength. Threats are what people resort to when they don't have the power to just act. Human beings don't threaten bugs; they just step on them.

So when someone comes at you with threats, keep that in mind. Often the threat is a tell, a sign that the person making it needs to scare you into complying because they can't just force you to.
