Could use the EBS to shut down all comms and have the armed forces round up the traitors for a couple of weeks...and explain it during progress.
I actually covered the EBS/EAS system on a couple posts a couple weeks ago.
In order for the President to use EAS, he has to pick up the phone to the Mount Weather command bunker. That is the head end of the whole thing. From there, it goes to the 44 PEPs (Primary Entry Points) that distribute it to the various regions and cities.
The Mount Weather head-end is run by FEMA. The person on that end would record the message (the President is NEVER live over EAS) then prepare it for distribution. If the message is sent, it is BY LAW to be distributed nationally.
HERE IS THE PROBLEM
The person (yes, a real person) can then determine if the
message is authentic. They can check with the military liason to see if something necessary of a national emergency is in play (i.e; inbound nuke missiles).
IF that FEMA person is Deep State or a Dem operative, they can choose NOT to send the message. Yes, that IS a possibility.
