Why does the state of Hawaii even need a man in the middle for issuing ICBM alerts. It would seem the military or at least something centralized at the federal level should be able to trigger this alert. Basically have it patched through directly. I can't see a benefit of an extra person in the loop. It could at best delay sending the alert, send the wrong alert. At worst is obviously missing sending the alert altogether. One might say, well one benefit is the state could prevent a bogus alert from being sent. But does the State of Hawaii have its own independent monitoring network of satellites or radar? I am guessing it doesn't.
