The DEFCON Warning System is an analytical reporting organisation which focuses on nuclear threats against the US and offers an alert code to the public based on current events. It is not affiliated with any government agency and does not represent the alert status of any military branch. The public should make their own evaluations and not rely on the DEFCON Warning System for any strategic planning. At all times, citizens are urged to learn what steps to take in the event of a nuclear attack.
