You seem to have the moral of the story as “we can not ever be truly prepared”
or as you say "Nothing is going to get us “ready” ".
I see a very different moral here though…
to me this says “brute force will not defeat clever strategy”
know only yourself and you will win half your battles,
know only your enemy and you will win half your battles,
know yourself and know your enemy and you will not be
defeated in a thousand battles.
I’m paraphrasing, but you get the idea.
what do I tell students about defense “on the street”?
First I tell them to avoid conflict whenever possible, because the outcome is always uncertain.
Then I tell them if they have to fight to use only the most effective technique they have and to get away as quickly as possible.
The best attacks are to the knees, groin, and eyes… also to the top of the foot.
in most situations an attackers weakest point of defense will be their lower extremities, and disabling these will prevent the attacker from giving chase.
a large number of the early self-defense techniques we teach include these stomping to the foot and kicking to the knee techniques.
everything changes when attacked with a weapon.
however, there is some evidence that, for the majority of people, carrying a weapon for self-defense increases the risk to themself when attacked. a weapon is not a replacement for the knowledge of how to defend oneself, it is only a tool and one that can easily be turned against oneself.
always remember that the first line of defense is awareness of one’s environment and potential threats.
