The briefcase is like the nuclear football

Shaw said President Michener had done one thing right , which was centralize the control of the weapon system.
Everytime she tried to attack Nathan James , she activated the briefcase .


The Open briefcase has computer screen and keyboard , two finger print scanner and a joystick
It require Shaw and one other Regional leader's fingerprint to activate it together .

It controls the missile system , the UAV drone .
that regional leader lady activated the brifecase and said something about using Nuclear on California .so i assume the brifecase also control nuclear weapon as well.

in the end President Oliver quietly close the briefcase .

That thing is like the stories about President's nuclear football , except it control other weapon system as well
