how do you pre plan something like this? Tell me.
One example: Identify all the targets you suspect of working against you using spies and wire intercepts in your administration then use the intel you have to orchestrate it. If you know a guy is going to stage a coup from the wire intercepts you let him stage it then trap him. You developed a list of your dissenters earlier so now you have a list to purge from your administration. What's left over are the like minded Sheeple who will follow your orders without question.
