US nuclear armada put on alert

EAM messages are encrypted and are not instructions, but references
to special protocols. For example, the commander writes to the
captain of a nuclear submarine to get a red folder from the safe and
see the algorithm of actions on such and such a page. Naturally,
without having a precious folder with launch codes on hand and not
knowing the ciphers, it is impossible to understand what is at stake.
However, by looking at the number of messages and counting the
number of printed characters in the text, one can roughly estimate
the level of military alert (https://twitter.com/SkyKingInfo).
The norm for EAM is the frequency of messages 1-5 times a week.
Sometimes, when there is some small crisis in the world, such as in
North Korea, the number of reports grows. Today, each message has
a length of a hundred printed characters, which worries observers.
At the same time, the number of EAM messages reached 20 per day!
We are talking about the headquarters of the US nuclear forces. It
is also reported that the US Navy has switched to radio silence
(https://bit.ly/3nR8afT).
