However, none of them were able to make the bomb before the Americans.īetween 19, the scientist, Robert Oppenheimer, led a group of experts on the Manhattan Project with the aim of making the world’s first atomic bomb.
These countries included Germany, Japan, the United Kingdom and the Soviet Union.
Other countries also saw the appeal in having a very powerful weapon that would prevent their soldiers being killed in large numbers, as well as being able to stop enemies from making possible attacks on them.

Roosevelt responded by setting up a group of experts to develop the idea in the United States. He told him about their ideas and the danger of the Nazis in Germany developing such a bomb for military use.
