Our choice not to harm, or do as little harm as is necessary, to the attacker ...
Ok, so even while my assumption was wrong - thank you for putting that right - this sentence seems to show that the outcome is the same:
Although the waza in your aikido are not designed to not hurt, nevertheless "not to harm or to do as little harm as is necessary" seems to be an aim that is inherent to your aikidō?
This is not the case in my practice. I have never heard that aikidō is about "not to harm, or do as little harm as is necessary, to the attacker" in my context. This has never been part of the teaching of aikidō in my biography. The aikidō I learned is simply not concerned with the physical health of an attacker.
While it is very concerned about how to deal with uke as someone who lays his physicall health in tori's hands and allows him to use his body as a feedback. So the intention of practice on the tatami is to help each other grow.
But uke is not an attacker.
