'Snow White' is a group of super computers that create complex electromagnetic disturbance signals that keeps you 'asleep'.
'Iron eagle' is a group of satellites that beam the electromagnetic signal to earth.
'The truth would put 99% of people in the hospital' because the system has a dead man switch/Samson option where the disturbance signal can be set to damage considerably your biology or your mental state into self harm and or suicide.
'It must be controlled' means that the take down of this system needs to be done in a controlled way to avoid triggering the dead man switch.
