"Sounds like the Ruskies have been studying such great Western culture as "Spies Like Us" and "The Piglet Files" as references to how to run a secret service organisation! What a bunch of muppets!"
Apparently a lot of the Russians who saw the interviews with the Salisbury tourists (which were shown in full on Russian television) were very relieved to discover that the security services are just as competent as ever.
In considering the success of Soviet spying one has to consider that Philby was English, Sorge was German, and Karla was imaginary.
