He is acting by instinct, continuing with the scenario of his aggressive behavior, yet all his aggression and physical efforts are turned against him and multiplied by the lever. He stands no chance.
To counter your model of behavior he has to be able to act counter-instinctively. But one has to learn that.
When we talk about learning we don’t mean training, but at least a short introductory course of effective behavior in a life-threatening situation.
Another example, if you are seized by the arm, what’s your first reaction?
Presumably, to pull away, right?
But is it effective from the point of view of the system we use here? What is expected of you by the opponent? What is he ready for?
Indeed, that you’d try to pull away, as a model victim.
What would catch him unawares?
He’d be surprised, if you won’t even think of pulling away, but will softly shift the center of mass in such a way, that the load at the place of the seizure will be reduced, and find the pivot.
The opponent will find relaxation at the place where he expects tension.
The only thing you’ll have to do then – to form the correct lever and apply the force in the right direction – the opponent will be dumbfounded. Moreover, he won’t even understand that he is not the predator anymore, but the prey. That’s how it works.
