> Aikido demonstration is cooperative. Uke and nage. Somebody throws and somebody receives the throw. I'm not one of those "Aikido is fake" people, but Aikido has no tournaments and isn't represented in MMA for a reason.

Judo and Jiu Jitsu have Uke and Tori for demonstrations. Same concept. Except when Uke gets thrown, they really get thrown. They will cooperate with the move but they aren’t providing the momentum.

I don’t know if Aikido is “fake”, but I do think it’s more of a performance than a martial art.

Judo and Aikido founders were pals in the military. There is a handful of koshi nague throwing techniques that are identical in both schools, and are done without any of uke's momentum.

Citation? They were contemporaries who knew of each other and apparently respected each other, including having students cross train across the test disciplines. I didn’t find anything saying they were military buddies.
