Nukes? There are such a thing as nationwide emergencies.

Honestly how could that be actionable in a short timeframe?

  It's about a 30 minute travel time for land-based ICBMs to reach the US from Russia or China. Let's say 10 minutes to get through the chain of command, and 5 minutes to send out the alert, so you might have a 10-15 minute warning. As absolutely mind-boggling as nukes are, I think people today credit them with more destructive force than they really have. For one thing, blast force goes down with the inverse square of of the distance. There's very much a diminishing return to bigger nukes, and the area of total destruction will always be much smaller than the area of sorta-destruction. So if you have a 15 minute warning, you can get away from windows or perhaps go to a basement or subway, There are plenty of ways to drastically increase your odds of survival if you are in the middle-zone of a nuclear strike. Any all out nuclear war is going to have a lot of people die. The purpose of national warnings and preparedness is to just make that number be smaller than it otherwise would be.

    There are 330M people in this country. How many of them have any idea what to do if an ICBM is on the way? I would be shocked if the number exceeded 330K. If anyone thought there were a credible thread of nuclear attack they would be taking steps of which a warning system like this would be a late step, not the first one. The local FEMA alert system is a good idea; the last time I personally found it useful was in 1989 (Loma Prieta earthquake) though I hear it works in more dangerous areas (e.g. tornado alley) and am not surprised by that. However here in the Bay Area its link to phones was ruined by spam (pointless interruptions sent to my phone) so I disabled it. This new system is worse. (BTW I wouldn't classify the false missile alert in Hawaii "spam". It was simply an error. But here I got messages that should have been on the news).

      There are 20.4 million veterans in the US, so on that basis alone I'd guess a little higher for the number of people who had an idea about what to do.
