Really, there should be no Plan B.
Plan A is Aikido, which is part of Budo, which theoretically consists of all possibilities. Plan A gives precedence to those actions that de-escalate, reduce harm, and resolve conflict. If my Plan B is a potentially lethal strike to finish the game, that’s just too easy–at that moment I’ve stopped practicing aikido and completely broken with Plan A. Was Plan A just a ruse or a trick? Why bother? Aren’t we just training? Am I really in any danger?
Plan B is also legally problematic. People die in relatively minor scuffles now and then, and the one left standing can go to jail.
There is a term from Alexander Technique called end gaining. It refers to the natural human habit of focusing on the end-point of our actions and becoming frustrated when we do not immediately achieve our aims. Consciousness of this tendency in yourself allows you to inhibit it and focus instead on the moment. The ironic side effect is that achieve your aims more easily and with less stress when you aren’t directly obsessed with them.
For me, the aggressive Plan B in aikido is a kind of end-gaining. It sets up a habit of escalation in more things than aikido. It reminds me that I’m thinking about *me* winning, not a win for the situation. That can carryover to personal interactions off the mat.
I remember an exercise from when I was about 12, in a karate class. Your parter shoves you, and you do nothing, but stand your ground. He does it again. You again do nothing. He does it a third time. You take him out.
This exercise is very basic for a reason–it’s for children. And I’m sure I learned a bit of calm and patience from it. But I also learned [unfortunately] that past a certain point you can stop caring for the other person and just win. This has been my impression of most martial arts (aikido excluded). The idea being that a good defense isn’t just a good offense. A good defense is a perfectly timed rapid-fire highly targeted devastating attack that obliterates your opponent. Our culture, especially action movies, seems to encourage this thinking.
Outside of Hollywood fantasies, reality is more prosaic and bureaucratic. Training for police officers and emergency responders includes considerations of levels of force. Justifications for their use are laid out in detail, and woe to the officer who uses lethal force in any but the most obvious of circumstances. A mountain of paperwork, mandatory time-off, and possible legal action awaits. This is as it should be.
In our day-to-day life often the most dangerous situation we deal with is getting cut off in traffic. There are few immediate penalties for just being a jerk. There is unfortunately no dope-slap angel to appear and correct us when we go over the line. But training to be compassionate in a violent situation can, I think, mitigate some of our negative, though natural human responses.
