I use this phrase so frequently that I am sure my students are sick of hearing it. I repeat it so often because it is so important. Most self-defense training consists of drills or techniques and it easy to forget because of the constant repetition that there is not necessarily a stimulus-response relationship between a technique and a situation.
A simple wrist grab has all manner of escapes, counters and other responses. Some martial arts seem to have a fetish for this attack, and all sorts of joint manipulations are built around it. Many students are surprised when I teach responses to wrist grabs that include strikes, knives, and gunfire.
Correctly they will point out that a wrist grab is not in and of itself a lethal threat. This is absolutely true, but in the totality of the situation it might be an element of a lethal threat. If the attempt to pull you into the van full of ski-masked assailants begins with a wrist grab there is certainly justification. The wrist-grab is not the lethal threat: getting pulled into the van is.
We need to remember that without a context we are just practicing a drill, trying to learn the technical aspects of a technique and not demonstrating a use-case. We are answering the “how” question and not the “when” or “why” questions. Knives and shooting are not my default response to a wrist grab, but they are certainly within my range of responses.
This can go the other way too. Some people think that the Teuller drill means that we need to shoot people with knives (or other contact distance weapons) that are within some fixed distance. A threat with a knife that responds to a verbal command of “Stop” might not need to be shot. I would certainly be creating distance and getting a weapon in hand, but if the verbal commands are working I don’t have a reason to shoot (yet), I just have an excuse.
The complete scenario (or as much as we can understand of it) dictates what the appropriate response should be. There are a number of models for making these sorts of decisions, and none of the good ones look like a list of “Attacker does x, I respond with y.”
