Defend with the utmost agression
We've already mentioned the element of surprise, which usually is
initially with the attacker. He expects a certain behavioral response on
your part now. The best thing you can do in this situation is the exact
opposite of what he expects, which coincides with the reaction that he
prefers the least:
You're going to attack your attacker with everything
You will go "mental". This doesn't mean that you start to swing your
fists around like a monkey on drugs, but instead you will ferociously and viciously
attack the weak points of your attacker.
Attackers HATE to be attacked! They are not used to having to defend themselves.
Knowing the weak points of your attacker is already half the fight won.
Most wanna-be thugs or attackers are not even aware of their own weak
points (except maybe their groin) so they wont make much
of an effort to protect these areas when launching an attack.
You won't fight in the way your attacker expects you
to fight, namely throwing around fists like randy cowboys. No, you will
unceremoniously use simple and effective techniques to instantly stop
the attack before you get hurt.
Society conditions us to use a measured response, if any.
We don't want to hurt anyone, not even our attacker, so we may just want
to block a few attacks, move away and hope he will change his mind and
cease his attack.
This is VERY unlikely.
In simple words: you must
attack until there is absolutely no more immediate physical danger from your
attacker. Let's repeat this: Keep attacking until you're absolutely sure there is no more
danger from your attacker.
This means, you will not just throw a few
punches. No, you will viciously attack the weak points of your attacker until you're sure you've created enough
of an opening to allow for a successful escape.
