They had gotten bloodied in a brief, undeclared war against the Soviets on the Manchurian border, though.
It's interesting that from our perspective in the West, that is, as Americans and Brits, Aussies, Kiwis and Canucks (no particular order there), the IJN was the bigger threat, with the Japanese Army in second place. That's natural, given the geography. We often forget about what that Army was doing. And there was also that dichotomy in Japanese strategic thinking. The Navy focused on the Pacific and the showdown with us, while the Army looked to the Asian landmass. They were also terrified of getting bogged down against the Soviets, on top of their campaign in China. We're fortunate that the Japanese military culture was so dysfunctional that the services looked on each other as enemies almost as much as they did us. If they had been able to agree on strategy, Japan could have caused much greater trouble than she did.
Prost!
