My strong impression has been that the Japanese military in the 1930s was a catastrophically-extreme illustration of Dunning-Kruger syndrome when it came to understanding international affairs and in particular understanding the psychology and industrial capacity of the United States.

(Admiral Yamamoto was a noteworthy exception: Having spent considerable time in the U.S, he strongly favored friendly relations with the U.S. and opposed going to war. When he was overruled by the militarists in the Army, he planned Pearl Harbor and Midway as a roll of the dice for what he judged to be Japan's only hope of success, namely by striking hard blows and trying for a quick negotiated peace. It didn't work out that way.)

It doesn’t stop them from going to war, but it makes it less likely.
