The American atomic bomb was built mostly by German Jewish scientists who escaped Nazi oppression to America. According to Time magazine, the Nazis would've had their nuke built before America if they hadn't lost the war.
Wanted to developer the atomic bomb before Germans
The invention of the atomic bomb did not occur until late in WWII not WWI. There was no such weapon as an atomic bomb in WWI, nor were their any planes that could have handled the weight.
No, not the Germans. The Germans were already defeated (May 1945) when the US dropped the first Atomic Bomb on Japan in August 1945. The Japanese moral was affected by the two Atomic Bombs used against them. This caused them to surrender.
because they knew if they didnt the Germans would
The Germans did not drop an atomic bomb on Japan or on anyone. It was the US which dropped two atomic bombs on Japan (specifically on the cities of Hiroshima and Nagasaki) in 1945.
The conception and the development of the atomic bombs were started in 1942 when Einstein contacted Roosevelt to warn him the Germans were dabbling in atomic bomb ideas. It was completely manufactured and ready to drop in 1945.
he knew that the germans were making an atomic bomb.
possibility that Germans were building atomic bomb
The US did not drop atomic bombs on Germany although the original purpose of the Manhattan Project was to develop a bomb before the Germans did. However, as the war went on Germany had to redirect recourses to other areas so they never succeeded in developing an atomic bomb. Once Germany surrendered, and the atomic bomb was successfully tested in New Mexico, the possibility existed of using it against Japan. And that is what happened
Einstein
Physicists world wide knew about the possibility for atomic power and atomic blast. They knew about it long before the Manhattan Project developed atomic power and atomic bombs. It was Physicist Einstien who wrote a letter to FDR to let him know there was evidence of the Germans looking into the idea of building an atomic bomb.
