The last first
Aikido was always about fighting ability...thats how you could control without fighting.
If Ueshiba could not fight....none of us would be here...including this site.
What he was trying to demonstrate was to be so good you could control without fighting.
I can't disagree with the above, but why have an art that's about fighting ability yet have nothing whatsoever in the art to test that ability? Even going back to pre-war or even earlier Daito-ryu, it wasn't there either, by all accounts. It makes no sense.
