The DEFCON Warning System is a private intelligence organization which has monitored and assessed nuclear threats by national entities since 1984. It is not affiliated with any government agency and does not represent the alert status of any military branch.

At all times, citizens are urged to learn what steps to take in the event of a nuclear attack.
