That’s simply not true. Trump could have seen the news on Fox and ordered a nuclear strike in retribution. Sure, the military would have said there’s nothing actually happening but IT WAS ON FOX. They would have been duty bound to obey him, right?
It was a mistake by the Hawaiian Early Warning System. Essentially some intern pulled the wrong tape for an Emergency Warning test. That’s it. The real fuck up is that the Hawaiian government took 38 minutes to call it off. The Hawaiian governor said, this shouldn’t have happened. No shit.
I could not find any confirmation on the regular media. But between Facebook and people on the street there were lots of people saying things. If Trump had an 808 (Hawaii) phone number he would have gotten the message from an official source.
I’d say given his impulsive behavior there is at least a significant chance that North Korea would have been nuked and North Korea would response in some way.
