Two words for you Michael, you ignorant fool: Tsar Bomba.
Apparently, that nuke had more explosive power than every single bullet fired, bomb dropped or artillery bombardment during the whole of World War II. Dayum that was a big bomb...
Right on. Biggest ever, and now totally obsolete. No need for a bomb that big with the targeting we have now. A point Kearny makes in the book I linked above.
