First off, I have a comment that sounds very foolish at first, but holds some greater truth if you bother and think about it in some depth:
Aikido does not deal with anything. No Aikido fighter will magically appear if you are under attack. It is you who will have to fight for yourself!
That is so very true. In a real fight it isn't your martial art that will define how you handle an attack as much as it is you. Brilliant observation/statement.
