Corona was deactivated a long time ago.  I've long heard about an archaic satellite(s) (CORONA), "owned" by DPRK which contained a small nuke (EMP).  Pole-to-Pole orbit in NORAD blind spot.  I'm wondering if we had been living under CIA/DPRK EMP threat for a couple generations.  What if said EMP was actually a CIA CORONA bird(s) controlled by the Deep State?  Can't exactly send up an ASAT to destroy it without people knowing.  WHite Hats must've found a way to disable it. Or there was a second Corona program.
