IIRC something similar to that happened during WWII....Even NYT cooperated.....This could be that level of national security.....
Those of you old enough to remember WWII (I'm not that old) can also remember (I've read of it) cities undergoing "blackouts" or "brownouts" of city lights, so as not to provide an attractive target to enemy bombers. Even railroads placed "shrouds" on their engines' headlamps.
Also, people of that time were admonished in various ways, through various media, that one should, in the interests of national security, CAREFULLY watch one's words.

It is very possible that some sort of censorship (not only self-censorship) has been imposed on our media outlets.
“Loose lips sink ships!” was another common statement that FR picked up when the conflict started.
The censorship explanation would explain why nothing but positive is coming out of the Fox network. They seem to be very careful about what they cover. Even the fact that Colms is leaving is suspicious.....Is he embarrassed in advanced and doesn't want to have to support the impostor?
