We're specifically examining the extent to which the 'aiki' skillset provides a technical basis for actual success in preventing harm.
I think you've misread my "intentions"
ANY "technical" skillset including Aiki as expressed in Daito-Ryu, Firearms, Nuclear Weapons ect ect ect
can provide "success without harm." Only a man bent on suicide would continue attacking someone who has "technical mastery" over him.
To me it's all about intention since the technical aspect of Budo as expressed in Daito-Ryu is a moot point.
