They announced an attack that requires a nation-state's worth of resources and
a years' effort (when you're starting from scratch), then said they'd wait for
90 days before releasing full details.  It seemed along the lines of the "do
not try this with your own aircraft carrier/faster-than-light spacecraft/
particle accelerator/nuclear reactor" disclaimers.
