I have not read the article but the quotes taken in their printed context have a ring of truth....and they seem to be stated in a non-judgemental manner.
Most martial studies are the examination of conflict in a controlled manner. Many aikido practitioners have turned away form the study of conflict and made aikido the study of cooperation. This is not a judgemental statement on my part.... Just an obversation. There is something that is lost when aikido is taken as a martial study on its own merits and it is forgotten that it is a derivative system based on combat.
just my two cents.
