The media outside Hawaii really brushed it under the rug very quickly, which I've seen a lot of people claim was suspicious.
Think about it from a psy-op perspective. If you're trying to wake-up a nation and trigger a 'great awakening' and you are going to do something as radical as to create a movie where there is a literal the-ski-is-falling/'precepice' moment being shown to the public, one where the EBS plays a DEFCON1 scenario, you're not just going to do that without conducting a localized simulation (like a localized ebs defcon moment in Hawaii) to gauge the public's reaction, see what sort of chaos arises so they can better plan for the real thing.
Just a theory that popped-into my head :)
No…. NSA data collection hub out in australia. Protocol states that in the event of a nuclear strike on any us state, all data is archived and sent mainland. It was speculated back then, this was a white hat op in order to get “we caught them all” level of data form the australia nsa data center… hence why the sounded the incoming nuclear missle alarm, then tried to say… oooops, our bad didnt happen.
