Here's a question for you Jase or anyone else who would care to explain this to me regarding the Cerberus device.

Why was there a countdown for this device Cerberus ( named for the 3 headed watchdog of Hell). Cerberus was supposed to be a fail safe for a nuclear weapon that was fired and needed to be stopped. I would think that would be initiated as instantaneous as possible.

Any real reason why such a device would have any countdown aside from the need to do so in the script?
