I love waking up a 2 and a half year old thread!
The belief that the US didn't have the stomach or was unwilling to use the A-Bomb in Europe is erroneous. Had the A-Bomb been ready well before Germany's surrender, I believe the US would inded have dropped the bomb in Europe, with the blessing of the UK and the Soviets. At the time, Germany was seen as the greater threat, who might have been making their own atomic weapon. As well atomic weapons were viewed as no different than conventional weapons, and there was a strong desire by the US military to use the weapon under the noses of the Russians. Had the A-Bomb been ready prior to the forseeable defeat of Germany, then Germany would have been a target.
