I am still surprised that the Japanese and Germans did not figure out their codes had been broken.

There must have been a lot of people who had suspicions.

But consider: for many years, US citizens who talked about ECHELON were considered crazies. Later, Bush's enormous surveillance expansion was mostly denied or dismissed. The 2016 Russian hacks of the DNC and the propaganda machine were brought up on national television during the debates. Yet there was denial, dismissal, and very little concern.

Without a plan for responding or reacting, denial is a very appealing way to deal with upsetting news. The Germans and the Japanese who were in a position to suspect that their communications had been compromised were also embedded in a totalitarian military chain of command, more focused on preserving the relative power of the people at the top than anything else. Questioning the efficacy of the system is easily cast as disloyalty. What could anyone do?
