Why is it called 'Def-Con 4'?

I think maybe because, after the war(post-apocalypse,) the defense conditions are reset, during the aftermath.

You ask "Why is it called 'Def-Con 4'?" to which I respond:

Why does it have a futuristic armor-suited skeleton buried in a snow-covered landscape on the cover?

Sense, continuity, and logic: three things not involved with making this movie.

You moron. It obviously came after the original Def-Con 1, with the sequel Def-Con 2, Def-Con 3, and then this movie. God!



I`m sorry for my lack of manners, but I`m not used to escorting men.

Funny you should mention David Lightman because Maury Chaykin, who played Vinny in this movie, was also in Wargames.
