Because they needed a weapon to defeat the Japanese, and many prestigious scientists, including Einstein himself, mailed the president to tell him of the potential power of an atomic bomb.
Albert Einstein did not invent the atomic bomb. He was a physicist who signed a letter to President Roosevelt in 1939 warning of the potential of atomic weapons and the need for the US to pursue nuclear research. The atomic bomb was actually developed by a team of scientists, including J. Robert Oppenheimer, as part of the Manhattan Project during World War II.
Never. It was invented and patented by Leo Szilard in 1934 and built by the US Manhattan Project between 1943 and 1945. Einstein's main contribution was simply to sign a letter Szilard wrote to FDR warning of the dangers if the Germans built one first.
No, he was a pacifist and worked on no war projects. His only involvement with the atomic bomb was to sign a letter to FDR that Leo Szilard had written, warning that the Nazis might make one first.The atomic bomb was not invented in the US or by Einstein, it was invented in London, England in 1933 by one of Einstein's friends - Leo Szilard while crossing a street and patented by him in 1934. What Szilard wanted when he invented the atomic bomb was only to provide a better way to transmute elements than was then available, but at the same time he did recognize its potential for a large energy release which might make it useful as a weapon.However it took 12 more years, many scientists & engineers & technicians, and an enormous investment in new industrial infrastructure before the first atomic bombs could be built.
US estimates suggest that 4.7 square miles of Hiroshima were destroyed.
Albert Einstein did not create the atomic bomb. The atomic bomb was invented by a group of scientists in the United States. The majority of the research and testing went on at the weapons research and design laboratory at Los Alamos, New Mexico. Einstein did, however, send a letter to president Roosevelt encouraging the United States to begin research on an atomic weapon, and many of Einstein's theories went into the creation of it.The atomic bomb was not invented in the US, it was invented in London, England in 1933 by Leo Szilard and patented by him in 1934. However it took 12 more years, many scientists & engineers & technicians, and an enormous investment in new industrial infrastructure before the first atomic bombs could be built.
He authorized its development by the US.
the us created the atomic bomb
If you consider the US atomic bomb is a Christian bomb, the French atomic bomb is also Christian bomb and so on, then you can name the Pakistani atomic bomb an Islamic bomb.
The US dropped the atomic bomb onto Japan on August 1945.
To defend against a possible Nazi atomic bomb!
The hydrogen bomb.

Fear that Nazi Germany might develop it first and use it to take over the world.
1945
The A-Bomb was invented in 1945.
Yes, both.
No bomb was dropped on Denmark.
