I'm not looking for an answer. I was merely trying to point out how aikido could be combat ineffective in certain scenarios. Because there are other martial arts like Jujitsu, and self-defense systems like Krav Maga that are specifically designed to counter these types of attacks/situations.
I see. I practice both jujutsu and Krav Maga and I feel that the training I have received may help me in those situations if they were ever to occur. I say may because nothing is 100%. The key to it is not the art itself, but the training methodology. By methodology, I mean things like scenario training, aggressiveness training, reaction drills and training under extreme stress and/or fatigue. If these elements are present in your art, then I think you have a methodology that addresses the concerns you stated. I'm sure there may be some aikido schools that train in this fashion.
