If you want to see a great example of why it was important, check out the
so-called 'Berlin Tunnel':

Some of the traffic that was intercepted was teletype traffic - which had
been encrypted. However, the equipment that connected the gear to the line
allowed a tiny electronic whisper of the original plain-text onto the line,
along with the encrypted form, and it was possible to read the plaintext off
the line with suitable gear.
