And the largest nuclear detonation of all time was the Russian Tsar Bomba, clocking in a 50 megatons, vice the 15 for Castle Bravo. The explosion broke windows over five hundred miles away. But even then, structures > 75 miles away mostly survived, so it still wouldn't have destroyed an entire state the size of Arkansas. And supposedly, the original design was for 100 megatons, but they dialed it back because of fallout concerns. http://en.wikipedia.org/wiki/Tsar_Bomba http://en.wikipedia.org/wiki/Tsar_Bomba
