I know loads of Americans and they're all ace but they're the first to admit they live in a strange country. Many states still regularly run full nuclear drills. Preparing for the apocalypse is a common hobby and prime time TV, more than 1 in 4 believe they will see the apocalypse in their lifetime and many would
like it to be in their lifetime.

Not to mention the paranoia it must to take to not be satisfied with having the worlds largest air force and needing to have the worlds 2nd largest(the US navy in case you were wondering) too.
