ENIGMA was prior to the CIA. There are wins, losses, and ties. What I'm saying that's not heard is that the US losses were orders of magnitude greater than the wins.

Walker - military codes and matters such as SOSUS. Enormous losses, huge. He's just one.

Ames - Everything the CIA had on the Soviets, all agents, all information. For years. The Soviets rolled up every agent in the Soviet Union, something like 23 people after Ames turned.

We got the odd person every once in a while, and some submarine wiretaps which were great but not real-time and not the sort of info passed by Ames.
