That's the number of nuclear weapons that have been set off so far, and the United States accounted for fully half of those.  Over $5 trillion has been spent to date on nuclear weapon development, testing and cleanup.  There isn't a single federal budget item that is more entirely without merit than nuclear spending.

Nuclear weapons have no other application than total destruction.  They can't be used for defensive purposes, peacekeeping, or even "surgical strikes."  There are no excuses for them -- not even the bad ones the government usually uses to justify excessive military spending.  And yet, when you add it all up, nuclear weapons have cost us more in the past 50 years than any other single program except Social Security.

If congress is sincere about wanting to cut spending, this is a perfect place to start.
