Except that Morihei Ueshiba specifically said that it was some of those things. Hence the problem
Really? Nothing of his I've ever read says that, though I'm sure there's plenty I haven't read.
.Of course, one could say that modern Aikido is different from what Morihei Ueshiba was doing, and they might have a point, but I think that most people would be loathe to admit that.
I don't think I have the authority to say what is and what is not Ueshiba's aikido, but it stands to reason that aikido has changed over time, as do all things.
