The thing is I don't see Saotome sensei being the attacker in that video. It was a bit more aggressive towards the attacker with strikes and whatnot but still.
I just don't think Ueshiba would support some type of competition like what's proposed by some in this topic. Maybe I'm wrong but from what I have read he seemed to be opposed to such things.
Now don't get me wrong...I'm no Aikido scholar but I have read a few things here and there and if I remember correctly he was no fan of aggressiveness or competitions.
I don't know...
He was no fan of sporting contests - but we're not talking about sporting contests, are we? The record is clear that both he and his students often took on people in other arts. That has nothing to do with aggressiveness or competitions.
