In order to qualify, it must be:

• Initiated by a US government agency or official.

• Sent to a broad class of people, such as all civilians in a certain state or city of at least 100,000 people. (With the exception of small groups of people such as those without a phone or who opted out of alerts.)

• Occur in the US.

If the alert was sent by mistake or for deceptive purposes, this resolves YES. If it was sent due to legitimate, reasonable concern, even if no missiles were actually launched, this resolves NO.
