If you really want a doorstop of a tome on nuclear weapons, checkout Rhodes' other book:

Manhattan Project cost nearly US$2 billion ($22 billion in present day value).(http://en.wikipedia.org/wiki/Manhattan_Project) It employed more than 130,000 people. Many labs and plants built in 1940s for the project are still in use today.

We have just spend $760 billion on so-called stimulus. The money is gone, and nothing to show for it.

That's how bloated gov't works nowadays, in CA, federal, and all other states. And the letter is calling for more of this!

PS Great book on Manhattan project: http://www.amazon.com/Making-Atomic-Bomb-Richard-Rhodes/dp/0...
