"I had an official position in the government and instructed at several military academies. The training at those academies was purely technical, focusing on the means of victory in battle. The guiding principle was "killing the enemy with one blow." Unfortunately, very few of those military men truly understood the concepts of loyalty and sincerity. Of course, there were some noble and brave officers who made great sacrifices for their country. However, the purpose of Aikido is to avoid killing another human being at all cost. It is never to be used for fighting and contention."

Interestingly, something I've found in my research into Kobu/Aikibudo of the 1930s is the seeming separation (or a recognition of the separate yet overlapping nature) of Ueshiba's aikibudo from his goshinjutsu (self defense arts).
