Re: What is "Aikido"?
To keep my comments more on topic, I suppose I should point out that I agree with HL 1978: aiki is present, and important, in higher level kendo. It's just a bit hidden from view because:
1) Kendo has its own terminology to describe such things.
2) It's high level stuff, so it doesn't get talked about much, at least not with us low level people.
3) It's used offensively, so it looks quite a bit different than it does in aikido.
