Remember what I said about intention? The same root movement, even the same technique can be used in many different ways. Any particular throw or hold can range from redirection to thumping falls to locking out the skeleton and breaking things on the abrupt drop. Most Aikido teachers stress a non-confrontational philosophy from Ueshiba's later years that seeks to control without harm or at most use pain compliance to provide a "teachable moment". Some schools such as the ones that teach police are a lot more rough and tumble. Same technique, different emphasis and application.
Personal opinion: Aikido shines brightest as a post-graduate course for the advanced martial artist.
In the application of all the aikido techniques there is the opportunity to add the atemi. The Aikido class I attend is composed mainly of high level karateka which is exactly the point you were making at the end of your post. I am learning the aikido to fill in the gaps not taught in the traditional karate schools.
The other point you made:
I don't want to cause unnecessary crap, but I do have to be honest with you. Most of the Aikido practitioners I've met, even ones at the instructor level, don't have that elevated level of skill. And the sort of training at a lot of dojos doesn't prepare them for it. That's a common failing in martial arts schools. It's a bit more of a problem for the Aikidoka. A lot of them - not all, but a big fraction - choose the Art in order to avoid the uglier realities of physical violence. Some are excellent, especially those who came to Aikido after a firm grounding in some other martial art as did Ueshiba and all of his original students.
Most aikido practitioners work with compliant partners. Their techniques are unlikely to work in the real world unless they use an atemi to distract the attacker. As you quite rightly say, this is not trained in most schools.
