Maybe a different take on the issue of co-operation. Use kuzushi in such a way that uke co-operates whether they want to or not. This seems to me to be one of the essential arts of Aiki to blend with the attack and then lead it in such a way that ukes attempt to regain balance and centre lead inevitably to the waza. To my mind this addresses the two current threads: "resistant ukes" and "false sense", since they are two sides of the same equation of non-understanding of the martial practise of Aikido. This is an intersting study.
