Actually, I agree with what was said in the interview, because here is what is being said, albeit the translation can be questioned:
: In Aikido, there is absolutely no attack. To attack means that the spirit has already lost. We adhere to the principle of absolute nonresistance, that is to say, we do not oppose the attacker. Thus, there is no opponent in Aikido. The victory in Aikido is masakatsu and agatsu; since you win over everything in accordance with the mission of heaven, you possess absolute strength.
I.e., O-Sensei is answering a question about the role of the Aikidoist and he stresses that an Aikidoist does not attack... thus the Aikidoist is not going to oppose an opponent. In that sense of no attack, I agree that there is no resistance to an opponent.
It appears Erick is ready an answer about the role of an Aikido response as meaning something to do with physics.
