Under different circumstances maybe.
No. By the time the US dropped the atomic bomb on Japan, Germany had already surrendered. While Germany did have a nuclear weapons program during the war, it did not actually get to the point that they were capable of building a working bomb.
They did more than consider it. The US dropped almost 1.5 million tons of explosives on German war targets.
Wherever the bomb is dropped a lot of people will be killed during the explosion and more from radiation for a long time after. Immediately after the bomb is dropped we will do what we have always done as Americans and go kick some a**.
No bomb was dropped on Denmark.
The US
To save millions more lives that would have been spent in a drawn out conventional war with imperial Japan, the scientists in the United States (ahead of Nazi Germany, who was also working on the atomic bomb) created the bomb to escalate the war with Japan. They ignored the first bomb dropped on Hiroshima, but the Empire of Japan decided they could not win and surrendered to the US shortly after a second bomb was dropped on Nagasaki.
Nazi Germany
The US dropped an atomic bomb on Japan and told them they would drop another if Japan did not surrender. They didn't surrender, so the US dropped a second atom bomb. The US then told Japan that they would send a THIRD atom bomb (which they actually didn't have. It was a HUGE bluff), and luckily for mankind, the Japanese DID surrender.
The city that tested the first atom bomb was in Alamogordo, New Mexico. If you are looking where the US dropped it on enemies, then it would be in Nagasaki, Japan
To end WWII.
Hiroshima
It is a GP Bomb (general purpose)
