"Multipliers', huh? Try this math:
Number of armed U.S. military personnel - 1.5 million
Number of armed U.S. civilians - 100 million
Now, you figure out what sort of multiplier the federals are going to need, to overcome those odds.
History suggests that a unified and ruthless armed force can subjugate a hostile population with approximately 1:100 ratio of fighters to civilians. It has been done before.
If the Nomenklatura currently running this country can maintain control of the Military and the armed Federal Agency forces, they might just be able to control 150 million people.
But that is a very big **if**. And it would not be enough to be sustainable for very long
I would count on TBPB to overestimate their chances and double-down on stupid.
