Checklist for a U.S.-Russia Cyberwar
“Should the rest of the world know what the response was and how Russia was punished? An obvious response is generally more likely to generate a counter-response because being punished and not responding could mean a loss of face before others. But a hidden response does little to warn other countries.
With Russia, the case tilts to a hidden response because the two countries have experience in covertly signaling each another (during the Cold War) when bounds looked as if they were overstepped.”
