How much was done to "meet the needs" of the consumers at the time, all very necessary I think to keep Aikido afloat in a very difficult time in Japan. And the "repackaging" of some of O-sensei's stuff in the more mystical vein also fed in to the stereotype of "mystical oriental arts" that still attracts many. And then notions of being one with the universe, peace, love, understanding, and all that good stuff that really started to kick in during the 60's and 70's. The timing was incredible if you stand back and consider it all.
Totally agree and, to some point, it explains why previous attempts to export Aikido were not so succesful. I'm thinking in pioneers like Abbe Kenshiro in UK, Mochizuki Minoru or Abe Tadashi in continental Europe or Tomiki Kenji in the USAF.
