Not to me, George. :-)
Atemi is implicit in every aspect of what we do in Aikido. Katate tori isn't an attack, it's a practice tool. It presupposes the strike with the other hand and people need to practice as if the other hand were doing that strike or they are totally open.
If I grab you and you begin to take my balance, what reason do I have for holding on? Why don't I just let go and break the connection? It's the knowledge that I am open to your atemi that forces me to keep the grab once I've committed.
When I attack and you enter, why don't I just hunker down and plant so I cannot be moved? I am forced to stay responsive by the possibility of your atemi. Saotome Sensei said that if you knew the other guy wouldn't strike you, all techniques would be stoppable.
Every throw you do in Aikido is a strike you are choosing not to do. The strikes are at the heart of the logic behind the whole interaction. That does not mean that you necessarily see them. I seldom throw an atemi in practice... but my students seldom put me in the position that I need to.
