Just as during WWII, during WWI, the British had a very sophisticated interception and decryption program[1]. Its capabilities were also kept secret for long after the war and the Germans remained largely ignorant of how thoroughly their codes had been broken. I think if the work during WWI had been revealed earlier, the Germans would have been more careful and would have avoided repeating some of the mistakes of WWI. It was shown to be a wise policy after WWI, so I&#x27;m not surprised that they continued it after WWII, especially with the start of the Cold War.<p>1. <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Room_40" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Room_40</a>
